I'd like to get my kids some active outdoor toys for Christmas and I'm thinking a swing. We have a good branch in the front of the house and a very stable pull up bar in the garage.

Is there any kind of swing that would work for both kids? Or set up that would enable us to quickly transition between "baby" swing and big kid swing? I'd like to be able to take anything we set up down fairly easily since it will be in the front yard.
