It may look like i changed a lot but actually she was on one from the hospital for a week and a half and the doctor said change to soy. she was on that for 3 weeks and became extremely fussy all day after drinking it.the doctor said try alimentum and because of her reaction the doc said stay on soy. I then switched doctors. The new one said try good start and she would not even take it so technically she never had it. Now we are trying sensitive lactose free.
