6mth, now w/ cow's milk allergy?

Is this possible. I've been eating dairy. On Monday night my ds developed diarrhea. I previously ate homemade milk based soup on Sunday. His diarrhea is green, foul-smelling, mucousy. He has no other symptoms, and hasn't changed his nursing patterns. I have cut out cow's milk, although i'm sure its crept into my system, as I have not read packaging. Anyway I decided to try a yogurt and within 2 hrs my son has the looks of an allergy ring, the skin is also raised on his anus.

Could this present itself now?

Yup, can happen at anytime. Sometimes, allergies are built up and the immune system has taken as much as it can. If you are positive that is the culprit, I would make sure that no dairy (even hidden stuff) isn't in his diet for a long time.
