Reasons for changing baby formulas

Our niece had to be put on a different formula but I cannot remember why. I think she was having an allergic reaction and they needed something that was easier on her tummy or something like that.

    Yes, I've had friends that could only feed their baby certain types of formula. One of my friends had a child that was severely allergic to all of the "normal" formulas and had to order a fancy formula that was shipped to their house
      We switched to Gerber Soothe. The regular formula made her very fussy.
