Has anyone had luck changing formula at 10 months. We have to switch DS to Alimentum due to an infection induced milk protein malabsorption problem. I don't know how he is going to handle that. If he refused it, the GI recommended slowly mixing 25% new/75% old, 50/50 and so on. Has anyone had success (ok- had it go well) switching formula at this point?
