when did your child grow oyt of their allergies?

[whyareallthegoodnicknamestaken]

Ds had a cmp and egg allergy that we know of. He's due to have allergy tests next week. He's 19 months now, just wondering if/when your child outgrew theirs.

ds is 12 and can eat cooked egg now in biscuits, but not too many biscuits at the moment because he still feels he can't eat too many without having symptoms.
