Whenever I saw those kids playing in sports(swim, football, baseball), they tried very hard but couldn't even catch up normal kids. I feel sorry for them. Their parents are not very shot at all. It is probably due to lacking of care from their parents.
My baby is 10 months old and has always been 95% in everything - weight, height and head size. I would love to see a slow reduction in her weight as she grows older. Compared to american babies, she is really chubby now. To me, the ideal weight would be around 70%.
