I was lactose intolerant as a kid and I still cannot eat cheese or yoghurt.
I also have peanut and soy allergies.
My childhood was hell.
Same.

- I was lactose intolerant as well. I still have egg and chicken allergies.
- Used to have oral allergy syndrome, and pretty much used to avoid most fruits and vegetables.
- Used to be sensitive to peanut, soy, seafood and beef.
Poor my parents, they honestly didn't know what to do with me. But alxamdulillah, I gradually grew out of most of those things except for the eggs and chicken allergies.
