There is malaria on the island, but long-term use of anti-malarials can cause liver damage, so no one living here takes them. I'm here with my 2 boys, and none of us have ever had a problem, we just use repellent with the mosquitoes are out. Plenty of ex-pat kids on the island. I think there's a homeschooling group in West Bay. Cam at Sandcastle Library has resources that she said homeschooling parents are welcome to use. If you want to enroll your kids in a school, probably the most popular choice is Esbir in Coxen Hole. Mine are at La Luisa in Coxen Hole, which is more affordable, but I supplement their English reading and writing at home, as the level at school isn't great.
