Zachary is now 58 inches tall and weighs 90 pounds I was just wondering if he is big for his age or not? I know he is taller than most kids his age at school last yr but should I be worried about his weight or not? He is wearing size 8 men`s shoes and 14 regular jeans and size 12 shirts. He has a 28 inch waist and an inseam of 24. I cannot believe how much he has grown just this summer!
