I'm am involved with the HMSA (being a sufferer myself) and they are always looking for funds. Loads of people suffer from HMS (Hypermobility Syndrome), children and adults alike, but it's still virtually unheard of. Check out www.hypermobility.org for more details.

Failing that, I think a children's charity or a homeless one is a great idea.
Merry Christmas all.
Love
