My wife and I have started taking our 3 year old to a new activity called “Tiny monkeys” that lets kids learn to tumble and jump and do all kinds of neat, fun things. 

I have to say, being a dad is definitely the funnest thing I’ve ever done.  Watching our tiny monkey running about the house (yesterday, she was saying she was a cat, the day before she said she was a sheep saying “Baaah” all the time).
