Week 8is when parent-recorded night wakings start to fall. Until then, families record about 1.7 a night.
Across nearly half a million babies there is no early drop in night waking: the weekly average sits between 1.66 and 1.76 parent-recorded wakings a night from week two to week seven, then falls to 1.06 by week 13 and 0.62 by week 26. Frequent waking in the first two months is expected across the whole population, not a sign that something has gone wrong.
Nights rebuilt from raw BED_TIME, WOKE_UP and NIGHT_WAKING logs (autotrack-generated logs excluded), converted to local wall-clock time with each log's timezone offset. A night runs from a bedtime logged between 17:00 and 02:00 to the first wake-up logged between 04:00 and 10:59, 6 to 15 hours later. Night wakings count if they start inside that night and last 10 to 90 minutes. Only wakings a parent entered are counted. Only babies who logged at least one waking at some point are included (families who track wakings). Each baby's average per age week needs at least three logged nights; weeks are then averaged across babies, one vote per baby. Nights from Jan 2025 to Sep 2026; 466,719 babies and 27.1 million nights in weeks 0 to 26 (9,136 babies in week 0, 20,985 in week 1, over 100,000 from week 8). The weekly curve edges up from 1.47 in week 0 to 1.76 in weeks 3 to 4, but that rise comes from which babies are logging at each age: babies seen in both windows averaged 1.68 wakings in weeks 1 to 2 and 1.66 in weeks 3 to 5 (25,658 babies), so the honest reading is a plateau, not a peak.
