The Resting Brain: It Works Harder Than You Think.
While our bodies rest, our brains embark on an intricate journey each night. Far from idle, the brain engages in a variety of crucial activities during sleep that are essential for our well-being and cognitive functions. In this post, we’ll explore in greater depth the five vital processes that occur in the brain during sleep. 1. Memory Consolidation: A Complex Process: Memory consolidation during sleep is a sophisticated process involving different stages of sleep. During slow-wave sleep (SWS), the hippocampus replays the day’s experiences, transferring information to the neocortex, where long-term memories are formed. REM sleep then integrates these memories with pre-existing knowledge, contributing to creative problem-solving and insight. This intricate dance between different sleep stages underlines the importance of a full night’s sleep for effective learning and memory retention. 2. The Brain’s Detoxification System in Overdrive: The brain’s waste clearance, via the glymphatic system, is not only more active during sleep but also more necessary than previously understood. The brain’s cells shrink during sleep, increasing the space between them by up to 60%. This expansion allows for more efficient removal of brain waste, including harmful proteins linked to neurodegeneration. This process is crucial for maintaining cognitive health and preventing long-term damage. 3. Synaptic Pruning: The Fine Art of Brain Optimization: Synaptic pruning is a more nuanced process than the mere elimination of excess connections. It’s a fine-tuning mechanism that enhances neural network efficiency. During sleep, particularly during REM phases, the brain assesses synaptic connections based on their usage and strength. This selective pruning optimizes brain networks for more efficient processing, learning, and memory formation. Sleep is a key player in brain plasticity—the brain’s ability to change and adapt. During sleep, neural connections are pruned and strengthened, and new synapses are formed. This aspect of sleep is particularly crucial during developmental years but remains essential throughout life, underpinning the brain’s ability to adapt to new learning and experiences. 4. Emotional Regulation and Resilience: Sleep is integral to how we process and respond to emotions. During sleep, especially in REM sleep, the brain reorganizes emotional experiences, often reducing the emotional intensity of memories. This process, sometimes called emotional regulation, helps mitigate the impact of stressful or traumatic experiences. It is also crucial for building emotional resilience, enabling us to face new challenges with a more balanced emotional perspective. 5. Brainwave Reorganization and Its Implications: Distinct patterns of brainwaves mark the transition through different stages of sleep, each serving unique functions. Delta waves, characteristic of deep sleep, are crucial for healing and rejuvenation. Theta waves, often associated with REM sleep, play a role in memory consolidation and creativity. This reorganization of brainwave activity is not just a marker of sleep stages; it actively facilitates various cognitive and restorative processes. The nightly journey of our brain during sleep is a complex and essential process, rich in activities that underpin our cognitive and emotional health. From intricate memory consolidation to the fine-tuning of synaptic networks, the brain’s activities during sleep are as dynamic and essential as those during our waking hours. Understanding these processes not only highlights the importance of quality sleep but also opens avenues for addressing various neurological and psychological challenges. By prioritizing and understanding our sleep, we can tap into its profound benefits, enhancing our overall mental health, cognitive abilities, and emotional resilience. The Truth About Teething and Sleep: What You Need to Know! As a Certified Pediatric Sleep Consultant, I often hear, “My baby is teething, and that’s why they’re not sleeping.” It’s easy to see why teething gets blamed for many sleepless nights. After all, the sight of swollen gums and the sound of a fussy baby can make us believe that teething is the culprit. But is it really? Let’s take a closer look at the facts surrounding teething and sleep and why waiting for teething to be over is not the best strategy when it comes to sleep training. Does Teething Really Hurt? Yes, teething can cause discomfort. As those little teeth push through the gums, some babies experience swollen, tender gums, which may lead to irritability. However, the pain from teething is often short-lived and comes in spurts rather than lasting for weeks or months at a time. According to the American Academy of Pediatrics, teething typically causes minor discomfort but not enough to disrupt a baby’s life long-term or interfere with their ability to sleep consistently. Can Teething Keep Babies Awake at Night? While a baby cutting a tooth may have the occasional rough night, teething is not the reason why babies wake up multiple times a night for weeks or months. Teething might lead to a cranky night or two, but if your baby has been waking frequently over a long period, something else is likely going on, such as sleep associations or a lack of proper sleep routines. Sleep training and helping your baby establish good sleep habits will ensure that minor disruptions—like teething—won’t lead to months of sleepless nights. The National Sleep Foundation supports this, explaining that babies who have learned to self-soothe will generally go back to sleep, even when dealing with temporary discomfort like teething. How Long Does Teething Last? Teething is a gradual process that starts around six months of age and can continue until the age of two or even three. That means if you wait for all teething to be over before committing to a solid sleep training routine, you could be waiting for years! Other factors like developmental milestones or growth spurts may also occur during this time, so it’s important not to let teething be the excuse for delaying sleep training. Teething is Not a Good Excuse to Avoid Sleep Training It’s easy to fall into the habit of blaming teething for ongoing sleep issues, but the truth is, teething is not the reason your baby is waking up multiple times every night for weeks or months. The real key to long-term sleep success is consistency. If you wait until your baby’s teething is finished, you’ll likely be waiting for over two years—during which time poor sleep habits can become even more ingrained. A Few Tips for When Baby Is Cutting a Tooth Yes, the teething process can lead to a rough night or two, but here’s the good news: if you’ve already established good sleep habits, your baby will get back on track quickly. Here are some tips to help manage teething while staying consistent with sleep routines:
Final Thoughts In short, teething may cause some temporary disruptions, but it is not the root cause of ongoing sleep issues. By sticking to healthy sleep habits and routines, your baby will be able to navigate teething with only minimal disruption to their sleep. So don’t let teething become the excuse to avoid sleep training—your baby (and you!) deserve the rest. Sources:

Because there’s a big difference, right? There’s all the babies, and then there’s your baby. And when it comes to your baby, the research and evidence can’t override your concern that you might be doing something wrong. Especially if your baby doesn’t seem to take to the new way of doing things right away. |
Well, sorry to be ambiguous, but the truth is, it’s complicated.
According to a 2007 joint study between Harvard Medical School and U of C Berkeley, “...a lack of sleep inappropriately modulates the human emotional brain response to negative aversive stimuli.”
Or, in layman’s terms, you’re likely to overreact when things go bad. So when, say, your baby starts to cry, you’re less inclined to think, “I wonder what she needs,” and much more likely to think things like, “I’m a complete failure as a mother.”
This is what happens after one night of sleep deprivation, so you can imagine what chronic lack of sleep over the course of weeks, or even months, can lead to. You may even be experiencing it right now. It leaves you feeling helpless, inadequate, and riddled with anxiety.
Alright, that’s the sleep deprivation part. Let’s look at the other major reason that this process can be so difficult, and the real elephant in the room when it comes to this whole endeavour. - Crying.
Will your child cry when you’re teaching them this skill? Here’s the straight answer. It is extremely likely, bordering on an absolute certainty that, yes, your baby’s going to cry when you implement these new rules around bedtime.
Is your baby also going to cry when they get dropped off on their first day of school? Again, we’re looking at about a 95 out of 100 probability.
Will you baby throw a fit when you turn off their favorite cartoons, or when they get their first taste of asparagus, or when they’re told not to eat dirt?
You betcha. And even though you know they’re not in any danger or genuine distress in those situations, you’re still going to feel your heart explode when you hear your baby crying.
But again, if we look at this objectively, we can see that there’s an actual reason why the sound of a crying baby causes us such distress, and it’s not because of the actual level of urgency. Dr. David Poeppel, Professor Of Psychology & Neural Science at NYU, found that a crying baby differs from other environmental noises in something called the “amplitude modulation rate,” meaning how often the loudness of a sound changes.
Crying babies, along with car alarms and police sirens, have a modulation rate of about 100 times per second, compared to a regular speaking voice, which hovers somewhere between 4 or 5.
Experiments with an MRI to monitor the brains of people while listening to a variety of sounds, Poeppel found that baby screams have a unique ability to trigger activity in… you guessed it, our old friend, the amygdala.
As with most instinctual habits, this one is more easily dealt with when we can appreciate not just what we’re feeling, but the science behind why we feel what we feel, so I wanted to provide you with that vital tool before you take on the challenge of helping your baby sleep through the night.
Now that you know; it's time to take that leap of faith and take the next steps in the journey to helping your little one learn to sleep well independently.
We can do this together!

- It’s going to be a challenge
- It’s going to be eminently worth it.
I’ve also never worked with a family who didn’t feel like they had made a tremendous decision once their baby had learned to sleep through the night. The benefits to the whole family are almost indescribable.
Like many big decisions though, there are times that are ideal and times that are less so. Today, I’d like to offer some tips for deciding whether or not it’s the right time to take this challenging, but oh-so-rewarding journey.
I don’t advise parents to start sleep training within two weeks of traveling, but I’m guessing that’s not a concern for most of us at the moment since we’re all sticking pretty close to our home base.
Is the time right for baby?
The best chance for a quick and effective solution to your baby’s sleep issues is to implement the changes when they’re healthy and thriving. If baby’s dealing with reflux or colic, you’ll want to get that remedied before you start sleep training. There’s going to be some fussing and protest in the first few nights, and we want to make sure it’s only due to the change in their routine, not because of actual discomfort, and if they’re healthy, it’s much easier to pinpoint the reasons for their fussing.
Is your partner on board? If you’re raising your baby with a partner, it’s important that both of you are committed to the process. This can be a trying ordeal for the first couple of nights and if your partner thinks it’s not a good idea, there’s likely going to be a point where they manage to convince you to give in and resort to whatever “sleep prop” you usually use to get your baby to sleep. |
I won’t sugar-coat it. Changing up someone’s sleep habits is almost never met with a lot of enthusiasm for the first night or two, so nobody’s likely to get a lot of rest for the first 48 hours. If you have an important meeting or a major event coming up in the next few days that you need to be in peak condition for, you might want to wait until next weekend to get things underway.
Are their accommodations ready? Exceptions can be made in certain situations, but I really do find that putting baby into their own room is the best way to help them learn to sleep independently, and there are a few decorating guidelines to help baby get the hang of this thing as quickly as possible. Their room should be as dark as you can possibly get it. |
Get rid of any mobiles, crib aquariums, or light-emitting devices that claim to help baby sleep. (I can assure you, they don’t.) An ideal nursery is flat-out boring. Baby should recognize it as a place to do nothing but sleep, so keep their toys and stuffies in another room.
Like I said earlier, now might not be the ideal time to take the initiative to help your baby sleep through the night. Getting started and having to stop because of some bad planning is likely going to cause some confusion and minimize your chances for success. But remember, there’s always going to be something that isn’t exactly ideal.

How are the older children going to react to this new baby? Are they going to embrace the role of being an older sibling? Will they turn into jealous clingers who need constant attention? Will their schedule fit with your newborn's naps and feeding times? Most importantly, how is this going to affect the older child's bedtime?
Trying to juggle two or three different bedtime routines can be overwhelming if you're not ready for it. Trying to find fifteen minutes to feed your newborn while at the same time trying to get your toddler out of the bath can make you lose your mind. Toddlers just know that you're in a position where you're unable to chase them down and enforce the rules, so they are more likely to take advantage of that weakness.
So here are some strategies for those of you who have two or three little people, and are struggling to find a bedtime groove.
Strategies to help get into the bedtime grove with a baby and a toddler.
- Have one bedtime for all the kids in the house. A lot of families I work with are shocked when I suggest that their three-year-olds should be going to bed at 7:00 PM, but at that age, kids still require between 10-12 hours of sleep a night, not including daytime naps. So if your toddler needs to be up at 7:00 AM, a 7:00 PM bedtime is reasonable. If the idea of having 2 or 3 bedtime routines at the same time seems overwhelming, keep reading.
- Team up and switch off if you can. If you're the lucky one and have a partner who's home and able to help you get the kids to bed, put together a list of what needs to get done. Split the tasks evenly, and then switch off every other night. That will help make sure neither of you feels like you have the short end of the stick. It will also get your kids used to either parent putting them to bed, so if one isn't available, it won't throw your them into a tailspin just because things aren't the same.
- Find opportunities to multitask. As a parent, either through talent or necessity, we become the undisputed champions of multitasking. Trying to get through two or three separate bedtime routines is going to leave you exhausted and probably won't fit with your schedule, so double up when you can. Let the kids bathe together, feed your newborn while you read your toddler a bedtime story, sing songs while you change baby's diaper. Wherever you can overlap, use that opportunity for all it's worth.
- Create and stick to a 15-30 minute bedtime routine. Bedtime routines are super important to get your kids to sleep through the night. It's not just a great way of giving them a sense of time; it also works as a signal to their brains and bodies that bedtime is coming. The routine stimulates melatonin production and turns things down internally to prepare for a long, rejuvenating sleep. A bath is a great place to start. It's a strong signal that sleep is just around the corner.
- Save a special activity for bedtime. Typically, the older child can entertain themselves for a little while so you can finish up with your youngest. It's not always the case, but if it is, find a non-screen-related activity that will keep your toddler engaged and quiet. Make this activity exclusive to that fifteen minutes that you need one-on-one time to put the baby down. Don't make it too exciting, or you could end up in a battle because your child's bedtime activity is too much fun to put down.
- Embrace child labour. Toddlers love structure and predictability. Giving them a helper position when you're putting your younger child to bed is a great way to keep them busy. Being a helper also gives them a feeling of triumph before they head to bed. Show them where to find the diapers and have them bring them to you when you're getting your baby ready for bedtime.
- Stick to your guns. Toddlers test boundaries in a constant, systematic fashion. "I'm not allowed to throw the football in the house? OK. Maybe I'm allowed to throw the soccer ball in the house!" And because you're attention is split between them and a new baby, you might feel a little indebted to them. That's OK, but changing or loosening the rules could end up upsetting them more, not less. As I said before, kids rely on predictability and structure. If suddenly they get the feeling like the fences are down, they typically feel a little lost, and that's going to lead to more tantrums, not fewer. So keep the routine and the expectations as close as possible to the way they were before their sibling arrived.
- No matter how bad it gets, no matter how tempted you might be, don't let your toddler watch a show. I know how putting your child in front of the TV or handing them your phone can buy you a few minutes of quiet, but screens can be the ultimate downfall. The entire time that they're holding your child's attention, they're flooding their eyes with blue light. That might not seem like a bad tradeoff for fifteen minutes to tend to your baby. However, blue light stimulates cortisol production and inhibits melatonin. So those fifteen minutes of peace and quiet could very easily cost you hours of trying to get your overtired child to settle down for the night.
- Accept the fact that it’s not always going to go smoothly. These are, young children we're dealing with, so if things start to go off track a bit, don't look at it as a failure on anyone's part. They're going to have regressions, rough nights, and occasional meltdowns. Staying calm and level-headed will be the best thing you can do to make sure these situations don't escalate into something more frustrating and upsetting for everyone involved.
- Embrace the peace and quiet. Once everyone is in bed, take at least five or ten minutes to let yourself unwind. Don't check your email, start a load of laundry, or catch up on whatever responsibilities you've got to look after. We all know that this parenting thing is a stressful gig. So when you get a moment to pat yourself on the back and find a little calm in your life, you should embrace it. The minutes right after the kids fall asleep are a prime opportunity to do just that. So take some time to celebrate the superhero that is you. There will be another night of challenges and rewards for the whole family right around the corner.
