WHAT’S INCLUDED

  • How infant sleep develops after 3 months — understanding how sleep cycles mature and become more structured.

  • NREM and REM sleep explained — the stages of deep, restorative sleep and the role of active, brain-building sleep.

  • How your baby’s body clock forms — what circadian rhythm is, how it develops, and how light shapes sleep patterns.

  • Day vs night sleep strategies — practical guidance on environment, interaction, and feeding to reinforce predictable rhythms.

  • Sleep pressure — how wake windows work, what happens when they’re too short or too long, and how sleep pressure drives rest.

  • Adult vs infant sleep comparison — a clear breakdown of why infants wake more, cycle faster, and rely on lighter sleep.

  • Wake windows by age — developmentally appropriate awake times from 3 to 12 months.

  • Sleep needs by age — total sleep ranges, nap expectations, and day–night distribution across 4–12 months.

  • Baby-led daily rhythm — flexible routines, following cues, and supporting sleep without rigid scheduling.

  • Typical day examples — realistic daily schedules for 4–5 months, 6 months, 9–10 months, and 12 months.
