When should I be concerned about my baby’s head size?
Pediatricians usually measure head circumference only in children under the age of 2, since the head doesn’t grow much after the fontanelles (soft spots) close at around 18 months. Again, head size is mostly genetic — so if you or your partner has a small head, your child may have a petite one too, and vice versa.
