Why this works
Built from widely cited child development and parenting guidance.
This playbook translates evidence-aligned principles into practical actions for one specific age and concern.
AAP
Infant sleep habit guidance in the first year.
Harvard CDC
Responsive caregiving and stress-buffering evidence.
Why this stage feels sudden
Sleep cycles become more mature around this stage, so babies wake more distinctly between cycles.
This usually reflects neurological progress, not parental failure.
What to measure this week
Track bedtime settling time, longest sleep stretch, and total night wake count for seven days.
Trend improvement matters more than one perfect night.
