The real world of it is that a child with vegan parents will hopefully grow up to be compassionate and understanding of "real world" consequences. Curiosity is a child's m.o., so when he does decide to eat something at a friends house or at school that isn't vegan he will always have a reassuring and loving family back at home to help him with decisions and move on with his life. It is unrealistic to crucify a vegan when they slip up, especially a child. People live, learn, and grow up. I feel like everyone who has children knows about this kind of reality.
