tina, i was just reading your post and you were talking about how small your boy is- 30 pounds at 4 years old. my son will be 4 in september and has yet to hit 20 pounds! he was diagnosed with RSS, which stands for Russell- Silver Syndrome. i doubt your kids have it, but hey, i thought i would mention it. they bone x rays and genetic testing and nothing ever came back. RSS is pretty rare and basically it's a mild form of dwarfism, mild meaning a lot of times people end up pretty normal height, they just start out small & skinny and take longer to get up there. anyway, just thought i would let you know that you are not alone w/the small kid thing. i actually couldn't imagine mine any different. crazy how things work, isn't it? anyway, God bless and good luck!
