My bub is breast and formula fed her formula is S26 so has cows milk in it so i thought the switch would not be a prob. For the last week i have been trying to get her to drink cows milk, ive tried adding it to her formula even the smallest amount and ive tried watering it down adding a flavour to it everything. After a few mouthfuls she starts screaming like she is in pain refuses the rest and ive just noticed a blotchy rash on her after i got her to drink about 50ml of cows milk being the most she has ever drank. She already has a heap of allergies Pumpkin, banana, strawberry, cat, talc powder, latex to name a few. I thought it would be ok she wouldn't have an allergy to milk because there is cows milk in the formula.
Can they still have an allergy even if it is in her formula ?
