Is anyone else child losing weight?? My son just turned 9 months old. He was always gaining weight but he started losing now, but he is pulling himself up and moving a lot more and we swim a lot through the week as well. Could it just be all the exercise he is getting maybe??? Anyone else having this issue, and maybe it's not an issue but it's scary when I think about it cause he should be gaining in my eyes lol. However, in saying this he is growing taller too so I'm wondering if he is just slimming out now abit too. Advice???
