My son who just turned 5 in march is just got on the Charts!! He has been at the 5th below on the charts for 5 years!! But now he is 5th at for weight and 10th for height. But he is still really small. My sister’s baby which is 15 months and my son can wear his clothes. And my nephew is very tiny baby he was 8 weeks premmie.so he is tiny but I can not believe that he can wear his clothes and i think that my nephew wears 24 months. I do know that when we went to riley they put in a NG Tube and that was HELL!! Sorry for the language but he was sick all the time. But we switched dr’s and he is doing well now. When he was born he weighed about 6.1 a nd when we brought him home he was 5.5 and had a very very ahrd time gaining weight!! But he is healthy and a very inergetic child and loves to play basketball. He says that he wants to play basketball, be a fireman and a dr. so he ahs some bigs dreams for a very small boy!! I wish you the best!!
