I agree

As they get older they lose the baby fat too, so they look more slender. My DS is 3 years 5 months and weighs exactly 29 pounds, but actually looks a bit chubby because he is quite short for his age. He has more of a stocky build where Nyla is very fine boned and looks very thin. I think that has something to do with it too. His wrists are already noticeably bigger than hers just because they have a different bone structure.
