My lb was prescribed nutramigen 1 three days ago for a suspected cow milk allergy, he broke out in eczema and had blood and mucas in his poops...he had taken to the milk fine, the first bottle was just a bit hard to go down...when I got up this morning his eczema had flared up worse than ever ...took him to out of hours drs...she give him a good check over said he is in great health otherwise, to give the new milk two weeks to settle...I've notice he isn't drinking as much as he used to when he was on cow and gate, he would guzzle 7oz bottles sometimes hitting 36oz a day...and today he has been very sleepy anyone else have this issue
