I have been feeding my one year old baby similac advance formula milk since birth but he is very sensitive and poops many times in a day. Doctor changes his formula milk 2-3 times in between to lactose free Dexolac nusobee. But when we come to similac advance the problem continues. Please suggest some other good lactose free formula milk as he is one year old now and Dr said not to give him cow milk as when he cannot digest lactose based formula milk. Please reply. Thank you all.
