Don't stress, apparently the asbestos isn't released from the wax until boiling point, well over body temperature, so even if they had been eaten, it is still fine, and I'm sure yours isn't the only child to put them in their mouth.cwe have the crayons and I'm sure my dd has put them on her mouth.
That's why they arent recalling them, if there was any health risk they would be recalled. Hope that makes sense.
