Hi, I have been reading some of the posts and I have a question. For those of you whose children were not diagnosed at birth, what let to the diagnosis. Were any of your kids not failure to thrive? My son is growing quite well, but there are some things nagging at me. He always has loose stools that smell bad. Not diarhea but just loose. He also has had the croup twice this winter. he's only 14months old and he's not in daycare so it's bugging me that he keeps getting colds. maybe i am being paranoid. he is in the %75 for height and %55 for weight, which is where he's been since birth. i keep asking the doctor about the loose stools and they keep assuring me that it's fine. I did dump one of his stools in the toilet once to see if it floated, someone told me that if it floated that meant that he might have a malaborbtion problem, and the poop sunk...I was just curious, do you think i should be asking more questions to his doctor?
