CDC milestone check
Tick what your child already does
0 of 11 ticked
The 2022 revision moved the bar from what 50% of children do to what about 75% or more do, so a milestone a child has not reached is worth raising sooner than the older lists implied.
Missing one does not mean something is wrong. What it is for: read those items out at the next well-child visit. This page does not diagnose, and it is not a substitute for a standardized, validated screening tool.
China’s warning signs, alongside
Warning signs published for 3 months
- No reaction to a loud sound
- Does not vocalise or smile when played with
- Does not look at faces or follow a moving person or object with the eyes
- Cannot lift the head when lying on the tummy
This list runs the other way from CDC’s: CDC lists what a child should do, this lists what a child still does not. Any one of them being true points to further screening — not to a diagnosis.
WHO motor attainment windows
None of WHO’s six motor windows are open at this age.
Where the measurements sit
