My kids want walkie talkies this year, so we'll be getting those for them. I also just signed them up for subscription boxes through
www.kiwico.com which I think they'll really like and I've been considering for a while. (If you happen to sign up through that link it'll give us both $10 off.
) I also got them
Hand-Sensor Ball Helicopters which should be a hit too. I'm still brainstorming/shopping, but they'll also get clothes, books, a few treats, and a game or two. My daughter's birthday is on Christmas as well, and I'm not sure at all what I'm getting her for that yet!
I hope you get some ideas for your family from everyone's suggestions!
