Re: Diaper rash or food reaction?
I'm no expert, but it doesn't sound like a food allergy rash to me. Usually, like you said it is around the anus. It might be just a regular diaper rash. Or, if she has thrush, it could be showing up as a yeast infection in her diaper area.
My lo has occasional inexplicable diaper rash, but it always goes away in a day or two if I just keep her dry and use Boudreaux's Butt Paste (or whatever diaper rash cream I have handy, but that works best).
