Fact or Fiction? Child Sleep Science with a Pediatric Neurologist and Sleep Specialist

There is a lot of terminology and misconceptions thrown around in the pediatric sleep world especially on social media. Can they self- settle? Are wake windows a real thing? And what about regressions? I welcome back Sujay Kansagra who is a pediatric neurologist and sleep medicine physician at Duke who has dedicated his life to helping kids (and their parents) sleep better. He knows sleep and the importance of it. He was on my show before on an episode called Sleep-training: What the evidence does or doesn't say. He joins me to discuss: If genetics play a role in sleep and if there is such a thing as a “good” or “bad” sleeper If “wake-windows” are evidence-based If there’s a certain age we would expect a baby to “sleep through the night” The truth behind sleep regressions To connect with Sujay Kansagra follow him on Instagram @thatsleepdoc and purchase his book My Child Won’t Sleep: A Quick Guide for the Sleep-Deprived Parent Additional Resources About Sleep: Review of Sleep Training Data: https://pubmed.ncbi.nlm.nih.gov/17068979/ Cortisol and Sleep Training Research Study: https://pubmed.ncbi.nlm.nih.gov/27221288/ Short Sleep Gene: https://www.ucsf.edu/news/2019/08/415261/after-10-year-search-scientists-find-second-short-sleep-gene "Sleeping Through the Night" Article: https://pubmed.ncbi.nlm.nih.gov/20974775/ Wide Range of Normal Sleep During First Year: https://pubmed.ncbi.nlm.nih.gov/12563055/ Sleep Regressions and Data Behind Fixed Months for Regression: https://www.babysleep.com/sleep-advice/what-is-a-sleep-regression/ We’d like to know who is listening!
