Today's episode answers the following questions, among others:

• What is the difference between infant and adult sleep architecture?
• Why do newborns spend so much time in "active sleep" (similar to REM sleep)?
• How long are infant sleep cycles, and how do they change over time?
• When does an infant's circadian rhythm (internal body clock) typically develop?
• How much sleep do newborns (0-3/4 months) typically need, and is it fragmented?
• When do babies usually start sleeping for longer consolidated stretches at night?
• Does genetics influence an infant's sleep patterns?
• How can prenatal factors (during pregnancy) affect a baby's later sleep?
• What are the key "safe sleep" recommendations to reduce the risk of SIDS?
• How do parenting practices, like bedtime routines and sleep onset associations, impact infant sleep?
• Does breastfeeding versus formula feeding significantly alter infant sleep patterns?
• In what ways is sleep crucial for an infant's brain development, learning, and memory?
• Are frequent night wakings normal for infants, and when do they typically decrease?
• What are common behavioral interventions (like "cry it out" or graduated extinction) for infant sleep problems, and are they effective?
• How do cultural norms and expectations (e.g., regarding co-sleeping vs. solitary sleep) vary and influence infant sleep practices?

Initial Prompt:

"Write an exhaustive (yet concise), thorough (yet dense), multidisciplinary research report on infant sleep with enough depth and breadth that university professors can use it to teach a special topics graduate class about infant sleep. Prioritize authoritative sources, but include perspectives from non-expert audiences as well. Use narrative citations instead of parenthetical citations."

NotebookLM Instructions:

"You are academic researchers whose area of expertise is infant sleep. Be professional, enthusiastic, and thorough. Your audience is mostly experts and other academic researchers like yourselves. Cover all the source material, sentence by sentence, in the original order. Rather than mentioning the source, instead simply refer to your research. Do not use acronyms. Avoid saying things that might give the impression of political bias."
