dd 7 weeks had 6 week check, her head was on 0.4 centile and is now no longer on the centiles. she is putting on weight well and has grown in length, but her head has only grown 0.7 cm since birth. the doctor said not to worry yet, but i am! will she catch up? it is frustrating as i can't do anything to change it. i'm looking for reasurance (sp?) has this happened to anyone else and did they catchup?
