If sleep is an important enough topic for national defense than surely sleep should be considered a serious topic for parenting!

Blog 162Best Advice for Long Night Sleep Durations

A 2022 review of 45 published peer-revied randomized clinical trials involving 13,539 children asked the question: What interventions work to help your child sleep longer at night. Every intervention regarding soothing strategies, bedtime routines, parent behaviors, physical exercise during the day for the child, and so forth was examined.

The answer: “Based on the best available evidence to date, earlier bedtimes offer a simple pragmatic strategy to meaningfully increase sleep duration.” The best interventions included earlier bedtimes and were associated with a 47-minute sleep extension compared with the remaining studies of only a 7-minute sleep extension.

  1. Dr. Marc, I hope you can help! My son is 5.5 months (6 months on 1/21). He has always been a good sleeper and for several weeks was sleeping 12-13 hour stretches with one, sometimes two wake-ups for feeds (he is breastfed). After the holidays, everything changed. He wakes up frequently – sometimes as often as on the hour – and he is quickly soothed with his pacifier, but keeps waking up. Since the holidays we decreased him from 4 naps to 3 and extended his day sleeps so that his first nap is ~2 hours after he wakes, and we try to add 10 mins to each wake window. His naps are slowly extending but are still as short as 30 mins and very occasionally over one hour long. Is this a sleep regression? How can we help him get back on track? Thank you for your help!!

    1. Please read the sections in my book on teething, wake windows, and sleep regression to fully appreciate why these are all bogus concepts. Please describe a typical schedule of naps and bedtimes. Have you read the age-appropriate section of my book?

      1. I did read the age-appropriate section of your book, yes, but am still not sure what is best because if I watch my child and not the clock then I’m putting him to bed more frequently than appears to be recommended because he always looks so tired at the 90-135 min. mark.

        Here is a typical schedule though it varies depending on nap times:

        Wake around 7am
        Nap 1 at 9am typically to 945 am
        Nap 2 around noon typically to 1245pm
        Nap 3 at 3pm typically to 345 pm
        Bedtime around 7pm

        I wonder if he is in need of the “Reset” that you describe in box #4 of blog post 140.

          1. He slows down. He is sometimes fussy and cries, but mostly just gets quiet and low energy around that time. If we do interact with him he might “wake up” a bit and engage, but if we were to leave him alone he’d just sit quietly or start to fuss.

          2. Your description tells you that his sleep tank is near empty (“slows down”, “gets quiet and low energy”, “sits quietly”) or empty (“sometimes fussy”, “starts to fuss”) because the falling asleep time is too late. Read the section on cumulative sleepiness to understand why this causes disturbed night sleep and review drowsy signs to determine when an earlier falling asleep time is best for your son. Does this help?

  2. Oh – a few other things – he is teething (has 1.5 erupted through so far). On 12/31 he had a terrible night of sleep, as his grandparents were watching him and bedtime was off and he couldn’t settle the rest of the night. On 1/1 he had a full 13 hours with one wakeup, but since then it’s been terrible. And the last thing to note is that he shows drowsy signs very early which is why he was still on 4 naps until recently. He seems to have a high sleep need for his age.

  3. Hi Dr. Weissbluth,

    We’ve been following your books and recommendations to help our son sleep since he’s a newborn. He is 27 months old and sleeps 11 hours solid at night, and takes a 2.5-3 hour nap during the middle of the day. One of the potty training method recommended to us is based on the book by a potty training expert named Jamie Glowacki. With regards to night potty training she recommends fluid restriction few hours prior to sleep, and waking up the toddler 2 times a night to prompt them to pee (until you figure out their night time pee schedule, then go down to 1 time, etc.). Our concern obviously is would this lead to habitual night time waking and sleep debt due to sleep interruptions? If this is indeed not a great approach from your experience, do you have some other recommendation for potty training at night (when day time potty training is completed)? Thank you kindly for your expertise.

    1. Sleep is essential for brain development.
      Toilet training was part of my 40 years pediatric practice: Nobody ever suggested fluid restriction. Opinions and claims, even by ‘experts’ without evidence should be ignored.

Bedtime: A Review

To better understand the importance of sleep timing (when your child falls asleep), appreciate the fact that there is a genetically controlled and automatic circadian sleep rhythm (Blog Post 112). This 24-hour rhythm of brain output is for sleep and wakefulness; it develops in infancy, and changes as the child develops.  Parents cannot change this rhythm.

Unappreciated Power of Early Bedtimes (#3)

A 2022 report studied sleep, depression, and brain development in children at about 4.5, 10, 12, 13, 17, and 19 years of age. They measured the volume of gray matter of the brain (representing the concentration of the cell bodies of the nerves in the brain). There was an “interaction between bedtime and preschool depression severity, indicating that children with the earliest bedtimes and the lowest levels of depression showed the largest gray matter volume.”
