I had to respond after reading your post Maybebabie

My DS was born at 35 weeks, and he was
2.325kg (5lbs 1oz)
44cm long
34cm HC

His head was, and is, enormous. He was such a skinny little thing as nb, but if I wrapped him all up in a blanket with just his head poking out he looked like a full-termer! LOL. His head has never been on the charts, ever. At his 18 month check it was the size of a 3 year olds . I just say it's to fit all his brains in . So MB, I hear you on the big head thing! Our scans always showed that he had a big head too.

Sorry DD, I know that doesn't help you much!
