HI, i'm new to this site and was surprised at how many other mums (not you) think their baby is overweight. I think your baby is great! My Jack was 6.35kgs and 61cms at 9 wks which put him at 90th percentile. My partner thinks we will end up on oprah with the obese baby!(he's just joking but!)He is still feeding every 3 hrs and we get 2x 5 hr sleeps (well average most nights). I'm now trying to push him to 4 hour feeds and its tiring keeping him amused (well walking around the house). The midwife at the clinic told me he was feeding too much, I think each baby is different and if they are hungry, well feed them. How can you put a baby on a diet already, its just crazy! My boy was born on the 12th so we'll see how much he has put on next week, he has a beautiful double chin and chunky thighes but who cares, hey!
