We have a trampoline, we bought it long before we had a gymnast. My daughter uses it for her jumps and more basic tumbling. We also have a built in pool so my kids are never in the yard unattended, there is always an adult out there making sure they don't do anything they shouldn't. They like to jump till they are nice and sweaty and then jump in the pool. Whatever you do if you get a trampoline make sure it has a good safety net. My sister's dog ate their trampoline net and she still lets her kids jump and flip on the trampoline. It makes me a nervous wreck and whenever we are there I have to be the bad guy and tell my kids they can't get on. That is one reason there is so many injuries on trampolines. Oh by the way one of the little girls in my daughters training group (7yo) fractured her growth plate handspringing on the trampoline in the gym under a coaches supervision, so it can happen anywhere.
