My toddler ate bit of a wax crayon that wasn't child friendly and his face started to go red in patches and get rashes. We managed to get most of it out and the redness has subsided. Should I still be taking him to a doctor for wax poisoning?

Yeah agree with the parent above. The rashes could just be a physical manifestation of his reaction to the crayons. There could be other sinister things happening internally... not trying to be paranoid but I'd bring my child to see a doctor if it was me.

In general, wax is not poisonous. If a child eats a small amount of crayon, the wax will pass through the child's system without causing a problem.

i would bring to the hospital for a check.
