Years ago (I do home childcare)..a parent brought me a prescription tub of stuff...they said it had Maalox, MOM and some other normal sort of ingredient in it. Guess what the prescription label said? Poop Goop....yup thats the pharmacys technical term! LOL It was sloppy-like and all white.
I have another current family now who brought me a similar prescription...called Poop-paste on the script label...but this one is more of a tan color and is very paste like..thick!
When my daughter was little (shes 16 now) she has major issues with yeast infections and sudden awful tummy issues resulting in flaming tushy. Back then the Dr said to paint her up with plain yogurt to sooth it, then we put her in cloth diapers when we were at home..loose and no plastic pants. For her, the breathing skin was a big deal. I think diapers are a bit better now tho???
You can ask your Dr or google it.
Good luck!
