When DS was starting cows milk, he would throw up any kind of milk except one particular brand I would buy. So I stuck with that brand. I was at the store on Friday and they were out of it, so I grabbed a different organic brand thinking surely he would be fine now that he has been on cows milk almost a year.

Tonight at dinner he vomited all over him self, but acted totally normal and fine. I dumped him in the tub and when I was drying him off noticed he had hives on his stomach. Should I be freaking out? He probably only had a sip of milk at dinner. He's acting totally normal but I'm keeping him up to keep an eye on him

Milk allergy or something else?? I can't imagine since he normally drinks milk.
