Over the past couple of months DS has become increasingly conscious of his weight, specifically his podgy tummy. He swims competitively and compared to the other members of his team his belly does stick out. However, he's not considered overweight so I'm not sure whether to encourage him to do a greater mix of exercise or whether this is just a prepuberty podge that will go as he gets taller? He turned 11 in May and is 5' 1/2". He weighs 99lbs which according to his school nurse and various charts that I've used is a healthy weight for him. He has very skinny arms and legs (knobbly knees) but his belly is big - his school trousers are age 12 with a 26 3/4" adjustable waist- they *just* fit him. On top of the general running around at play he swims 4 times per week for 1.5 hours each time, plus 1 hour land training plus 2 hours school PE (currently gymnastics) and 2 hours school games (currently run a mile warm up then basketball) and a swim competition every 2-3 weeks. He eats well - very little junk food and no soda. When he's clothed he doesn't look overweight but if I'm being objective, in his swimming trunks his belly is quite a bit out of proportion and I can see why it's bothering him so much. I just don't know whether to sort of ride it out and see what happens as he gets taller or whether it is something he should worry about (the school nurse doesn't think so)? He's always been built this way - he was premature and I swear he looked just like ET as a newborn! However, while he really didn't care before, he's now getting very self conscious.
