Everything I've read says yogurt and keifer are ok for babies. I have bveen giving it to her without any problem.

The trouble is she has a ton of dirty diapers, and a diaper rash that keeps coming back. I don't think it's related to the dairy at all because she gets it even when not getting a bit of dairy and before she started table foods. I do notice it is much worse on days she has any kind of baby cereal, so I'm starting to wonder if those are the problems.

The formula is more for the nutrients and higher fat in the formula compaired to milk. My worry though is formula goes bad so fast I wonder if keeping it at room temp while it cultures could make it dangerous.
