how old is she? could it be teeth?

My 15 month old DD had same thing, and i was worried about food allergies/intolerances but when we went to the mchn, she thnks it is cos she has 4 eye teeth (i think that's what they are called) coming through. it also gives her a rash on her face that comes and goes.

I usually use cloth nappies but when DD has had the nasty rash i have gone to disposables so i can use a barrier cream like bepanthanon or the other white one you get samples of in all the baby bags. They seem to help clear up the rash quicker than paw paw.

hope she feels better soon.

ETA- just a quickie, are you breastfeeding? i see that your new bubba is nearly due, if you are breastfeeding, the colustrum could be affecting your DDs poos.
