I think it depends on the child. Allergies are a confusing area to deal with so maybe ask your doctor or childhood nurse and they can examine your child as well to determine more .

I think it differs for kids depending on their own allergies. I have 2 friends – one of their kids has grown out of their intolerance at about 1 year but the other friend’s child is still highly allergic at age 3.

haven’t experienced this but maybe ask your doc next time for advice about it.

some family members had this and grew out of it by the time they started school

Found out my son was allergic to eggs when I made him a boiled egg with soldiers when he was still in his high chair – so about 12 mths…. He projectile vomited! Wow, it was quite a show LOL. He couldn’t tolerate raw eggs, omelettes, etc or even lick the cake bowl and spoon!! Honestly it wasn’t until late teens for us. He is 23 now, and can eat scrambled eggs, but only once a week, or he feels sick still. Must be from the build up.
