Baby's head circumference percentile
Today we went to 2 months visit to our baby's pediatrician. We are concerned to find that her head circumference dropped from 54th to 16th percentile in 1 month, which seems to be a huge drop but the pediatrician doesn’t seemed to be concerned. Although she mentioned baby is not as smiling or interacting as she should be. She is smiling but I agree it's not much.
Has someone experienced this and how's the baby doing?
