We have had my 11 month old son on sensitive formula since day one. First Similac, then switched to Parent's Choice around 6 months, which went great. We did attempt to switch him to a regular non sensitive formula, and it did not go well - he reacted terribly and had horrible diarrhea for a week. For those that have switched from sensitive formulas to milk, did you find that there were any issues in how they tolerated the milk?
Re: Will baby on sensitive formula have problems with milk?
It's really trial and error, because every child is different.
