We got Aptamil Pepti 1 and 2 for our little girl with a cows milk allergy and it's prescribed by her doctor. She's on oat milk now but she was on the prescribed formula until she was just under 13 months. She had to get seen by a dietician so they could see her reaction to cow milk first, but it all happened quickly
I think so but I'm sure it would need to be approved by a paediatric dietician first
