Questions parents ask
What should a 9-month-old be doing?
By 9 months, most children (75% or more, per the CDC): is shy, clingy or fearful around strangers; makes different sounds like “mamamama” and “babababa”; gets to a sitting position by themselves.
What if my child isn't doing all of these at 9 months?
Tell your pediatrician at the next checkup, or call sooner if you are worried. Each item is something most children do by this age, so a missing one is worth discussing but is not a diagnosis. In the US, you can also contact Early Intervention (under 3) or your school district (3+) directly for a free evaluation.
