#asktheexperts good morning doctor! my 2 months baby yesterday vomitted the whole milk which she drank from afternoon. yesterday I had to leave my baby at home and went out due to some professional commitments, I fed my milk to the baby while leaving and left 40ml of milk so that I can return back within two hours. Since the baby was hungry and already drank my milk in the bottle, she was fed with powder milk of 30ml. she was already having some congestion sounds while breathing due to cold so we used nebulizer after coming home. immediately after that she vommitted the whole milk which she drank since afternoon. Please let me know the reason, is this because of cold and phlegm or due to powder milk which was fed due to emergency.
