Baby Formula?

Yea, you should stick with one kind if your going to feed your baby formula, but she might not react good to one or another, so keep a few on hand just incase you need to switch her, i'd start off with the one that has higher iron i think that's what they told me the baby needed first.

I asked the same question when my first child was born. The answer I got was that I should try to stick with one type of formula. This includes different types of formula even though itis the same brand. I was also told that switching formulas, if we had to, would not hurt the baby, but like you say, would just irritate the baby's digestive system temporarily but they would eventually get used to it.
