My baby head circumference at 15 month check is only 3% . But at 9 months it was 9. My baby is very active kid and she can able to speak some words ,walks well and actually run everywhere,sensitive and shows her body parts pretty well. Actually I dint give her milk/ very less for 4-5 months and I feel may be because of it her head growth slow down. Now again I started milk with dha and formula too. So please let me know ....what I can do to make her growing.
