Quoting MommyToWesley:" Slowly introduce the cows milk, or you could give her a lot of tummy troubles. I would go to a step 2 ... [snip!] ... go to a step 2 formula or goat's milk, but that's just me. I don't want to really give my son any milk until around 2 years."
Thanks! She has a real sensitive stomach so I may have to hold off on it. I can try a step two, but hopefully she takes to it like the formula she was previously on. She's outgrown her colic so there's a possibility.
If she did have cows milk for a taste, it's supposed to be whole right?
