What these numbers mean
Starts
~wk 74
The average age babies first begin showing early signs of this skill. Before this, it's simply too early — there's nothing to worry about.
Median
wk 91
The midpoint age: half of babies have reached this milestone by here, half a little later. It's a typical target, not a deadline.
Std dev
±6 wk
How spread out the timing is. About two-thirds of babies achieve it within one standard deviation of the median (the shaded band, wk 85–97). Wide bands mean a normal range of variation.

A gentle check-in point. If your baby hasn't shown this by around here, it can be worth mentioning to your pediatrician — most often it's still perfectly fine, just later.
About this milestone
Maintain consistent wake windows of 5.5 to 6 hours and manage sleep regressions through firm, comforting routines.
What to try & how to support
- 1. Plan for exactly 5.5 to 6 hours of awake time before the midday nap and before bedtime.
- 2. Keep up a predictable, comforting bedtime routine (such as bath, reading, and cuddles).
- 3. Offer quiet rest time in the crib if the toddler goes through a phase of resisting their nap.
What to avoid & gentle reminders
- 1. Avoid moving the toddler out of a secure crib into a toddler bed prematurely during an active 18 or 24-month regression wave.
- 2. Avoid using electronics or screen time within 1 hour of sleep, as blue light inhibits natural melatonin production.
- 3. Do not abandon standard boundaries under protest; consistency provides the emotional security needed to resolve sleep issues.
