We're slowly introducing our 12 month old to whole milk. He drinks it fine, though slower due to being shocked by its coldness. Afterwards, sometimes minutes, sometimes hours (after nap), he'll spit up. This happened both when drinking it straight and mixed with formula.
Also, he's started having what looks like a rash on each side of his mouth...I was wondering if rosasia (sp), but now wondering if it's milk related because it did start about that time.
