My little boy was born weighing almost 11lbs and he’s always been a hungry baby. He hasn’t been weighed since he was around 4/5 months but he had always been on the 98th centile. He is very tall for his age, judging by children older than him that are near to his height. His current weight isn’t 100% accurate as it was weighing me then me holding him but still, 2 stone seems a lot for his age. Should I be concerned?
