My 19 month old has a rash that has been persistent for the past 2 months. We have tried antibacterial ointment, antifungal ointment, all diaper rash cream, corn starch, baking soda, changing diaper brands. I'm sick of this. I feel so bad for the little guy, it obviously bothers him, we have to keep him in pants or he tries to dig at it. His doctor said we can't run any tests until it blisters or has puss to collect for samples. Two other doctors said it was any yeast infection, but it's clearly not or the cramps would have done the trick. I would post a picture but don't know how. It's now spread to his arms legs and tummy. Anyone please help!
