Metabolic question allergic to own drool?

[Guest guest]

I find zacharys skin to be kinda on the odd side. He gets the worst

bumps/rash around his mouth from his drool and I am wondering if it

could be caused by the metabolic make up and it be a bit more toxic

then most just curious cause his rash can be quite bad i am

constantly putting a & d. It was wierd too the other day he had

barbeque sauce and Usually its fine but he got bbq sauce on one spot

on his face and I whiped it off and it left a burn mark/little welt

where the sauce was . is it cause hes " thinned skinned? " or is it

because his sensitivities i am just curious ty.
