Can an egg intolerance take ages to make a child sick?

[wangle99]

DS who is 4 has an egg intolerance (not allergy), gives him cramps and vile poo.

DD doesn't have any intolerances that we knew of, however, twice now when eating slightly over cooked eggs she has been sick. (they were meant to be soft boiled but had started to set)

Am wondering if she has got intolerance too. She had eggs last night for tea at 5pm and was sick at 7am so quite a while.

I think i'm praying its not a bug lol but also just am beginning to wonder if it is the egg doing it.

my DD, who is now 15 and has a full blown nasty egg allergy complete with epi-pen, started out by being sick when she ate egg as a toddler. The reaction just got worse and faster and more violent so we gave up on egg and had her tested.
