I knew my baby was bigger than alot his age when I went to my postnatal group and found he was the same size as the babies that are 3 or 4 weeks older than him. Today we went for our 6 week check ups (slightly late because he is 9 weeks on Thursday) and turns out for his height he is in the 98th percentile for his age. I wasn't overly surprised but the doctor was!!! So looks like my boy is a tall one! Perhaps he gets it from his Uncle or Great Grandad, my husbands brother is 6 ft 5 and their Grandad was 6 ft 7. He is 63 cms I think. For his weight he is in the 75th percentile, which isn't surprising due to his height. He looks so much older than the other babies that are the same height and has done for ages, he didnt look like a newborn for long at all. Bless him he's sturdy!! Who he is 13 lbs 7, and was 7 lbs 9 at birth, so wasn't exactly big.
