A note on cow's milk allergy vs lactose intolerance:

"Since cow’s milk allergy involves the immune system, babies who are allergic to cow’s milk protein will also show allergy symptoms like an itchy rash, wheezing, or runny noses and coughs. These aren’t seen in lactose intolerance, as this condition doesn’t involve the immune system."

Another difference is that with cow’s milk allergy, even a small amount of cow’s milk protein could give your baby an allergic reaction. In contrast, many people with lactose intolerance can often eat small amounts of milk products without noticing any symptoms."
