I plan on starting to wean soon. But I have a concern about milk senstivity. I have given my ds yogurt and small amounts of milk and soon after he spits up horribly and he has loose stools. It dosnt seem like vomit to me. He has had problems with spit up but has pretty much stopped when he was about nine months old. He will be one on the 20th. Does this sound like a milk allergy to you? I am concerned about soy because it dosnt have the fat that babies need for brain development and I am not sure I want to nurse for another year. Will he get used to the milk and stop the spit up?
