Evidence-based Baby Sleep With That Sleep Doc (Part 2)

30 de septiembre de 2026 · 38 min

Notas del episodio

Welcome back to part two of our 100th episode with That Sleep Doc, Dr Sujay Kansagra. He's a child neurologist and sleep medicine doctor at Duke University and the inventor of the Lullabee smart crib mattress. This half is where Bec finally gets to ask about a real bugbear of hers, low sleep needs, and Sally asks Sujay to diagnose her. We get into what actually decides how much sleep our babies need, why six hours of naps won't give you a twelve hour night, whether overtiredness is really a thing and how Sujay copes with the trolls in his comment section. Then it's a very slow fast five, the Lullabee versus the Snoo and the biscuit question we promised you.
