Time to HOMESCHOOL your kids. Bullying? Come on - I bet the school won’t do anything!!
It's not a good choice in this case. Children need to learn how to live in a society, the younger they can cope with this, the better. In adult age they'll meet the same, but things will get more complicated. One'll feel nostalgy on simple school-time fist-fight.
Awwwwwww, jeeeez. Won't they miss out on all that cool socialization? [/s]
