Ds is nearly 4 and is on the 98th centile for height and weight (he's always been between the 91st and 98th since he was born-is in nursery but taller than a lot of children in reception). He's heavy but in proportion, has size 13 feet and is going to be a big tall boy. My concern is his pot belly! You can see his ribs and his spine, his little arms and legs are lovely and slim and he's not chubby in the face but he still has the slightly protruding tummy when he's standing up. Is this normal? He's very very active and fit, runs around all day and is in the right aged clothes. I was just wondering if this is something I should be worried about...
