DS took prevacid and was on Alimentum. We never tried nutramigin. Our pediatric gastroenterologist suggested Alimentum so that is what we used. I remember it took several days for DS to get used to it. We got it at our local grocery store, but they didn't stock it all the time, so we had to order cases of it from them to make sure we had enough. I remember it only came in 1 lb cans of dry formula and it was around $23 a can. I have seen it ready made in 8 oz cans but it was very expensive. I remember DS would go through 3 cans in a week, so it cost us $75 a week for him to eat (he was on Alimentum from 2 months to 12 months).
