Hi we changed our baby’s formula from Aptamil to kendalmil today and he has been crying and screaming pretty much non stop since the switch. He’s 3.5 months old. We did it one go rather than slowly introducing the new formula. Is this reaction normal? I’m not sure how long to carry on with it for. My plan was to give it a week to see if he settles with it, but I’m not sure if that’s too long now?
We are trying the switch because he was really unsettled and had digestive problems on Aptamil and we heard good things about kendalmil.
