My 13 month old son has recently been having stomach issues. This seems to get worse everytime I give him milk, he was bottle fed from birth as I could'nt breast feed and drinks SMA & has never changed formula. He has constantly been having diarrhea & only stopped when I stopped giving him formula. I contacted our local doctor who said it was a phase and would eventually pass. The problem is, the diarrhea was so bad it gave him rashes & that was a horrific experience. Does anyone have experience with this??? baby suddenly going off formula milk, I am not sure because he has been fine up until now... help...
