Hollo, i think it might be a coincidence. Allergies tend to appear as rashes, redness around the face etc. Intolerances tend to lead to runny poos/spews etc. Also after 5 mins, the food hasn't been properly digested. My DD who is a similiar age to yours, is also egg allergic but her pr!ck test went from 7mm at 12mths to 11mm at 2 years. I have been giving her very small pieces of cake/biscuits with egg in it and on some occasions she gets a bit of a red rash and other times nothing. Dr said its important to keep giving it to her so she will hopefully grow out of it.

I would give it a go maybe once a week and see how you go. If giving her homemade things, try to chose ones with only 1 egg as there is less of it within the cooked product IYKWIM?
