I sponsor a child through SOS Children's Villages. I get one letter and photo a year letting me know how they are doing, written by a regional manager from the charity, not the child, and usually one other letter a year thanking me for sponsoring and asking me if I'd like to give money to a special project they are doing. I always ignore the latter letters and have never bothered to write to the child I am sponsoring. The charity doesn't encourage it but you're allowed to if you want to. I've been doing it for about four years now and have got through three children as two of them have been reunited with someone from their biological family so they allocated me another child. It's just the right amount of interaction for me - one update a year, if the child doesn't need help any more they automatically allocated me another one. I don't need to be hugely involved with the child, or for them to feel like they have to write to their sponsor all the time because they owe me something. I'm happy just to send the money, know I'm helping, and let the child get on with their life.
