Age? Would you accept a 15 year old as very interested

Personally, I think 15 is a bit young. When I was in Malawi we had a girl who was very homesick and a bit immature and I think from memory she was 17. However I am pretty sure not long after I left Naturally Africa did take on two 15 year old sisters. So I guess that's a bit different as the have each other. I think one did sport and the other one was in the nursery.
I would be very hestitant about accepting a 15 year old.

I think the age is 18+ but you should get in touch with naturally Africa volunteers directly for that sort of information as I was just a 2 week volunteer.
