Hello girls, can you tell me when you stopped giving formula milk during the day and started offering more purees, from what age? We're actually getting more formula than usual, and our formula is therapeutic, we don't get better normally. Can you advise on how to stop feeding formula during the day? And generally, do we need to stop or just give less? I don't know how to do it right ?‍♀️ The pediatrician says to continue both formula and purees, but she doesn't eat that much!
