I am not sure which forum to post this question in. I am trying to figure out what is bugging DDs tummy. She is about 75%BF and 25%FF. Nothing has changed there in the last week or so. She isn't on solids. She doesn't seem to be drooling any more than I would expect, so I am not sure about teething. No one else in the family is having problems, so I somehow doubt it is a tummy bug - she isn's mouthing things much on her own yet. This week, she has been pooping a lot and each poop smells funny and is quite acidy. I have been slathering her in Zincofax and it helps, but nothing will make the rash go away until the poops get better. Any thoughts?
