Show Notes

Dr. Michael J. Breus talks with Stanford sleep specialist Dr. Rafael Pelayo, author of How to Sleep, in a "grand rounds" style conversation that spans kids' sleep from babies to teenagers. Dr. Pelayo explains why parents should agree on a sleep and feeding plan early, how to spot pediatric sleep apnea, and why he's skeptical of melatonin and other supplements for kids. He also makes the case for later school start times, explains why sleeping in more than two hours on weekends signals sleep deprivation in teens, and shares why the content of a screen may matter more than its blue light.
