Re: fitness for a 3 yr old. just keep them outside?
I've got three-year-old twins. They play outside. They imitate some of the things they see me do during a workout. There is no plan or instruction. Kids that age are naturally active.
One of them climbed a rope unassisted this morning. She has seen the rest of the family doing climbing it, and I've helped her many times before. Today it clicked for her and up she went. Would I ever TRY to instruct a three-year-old how to do that? Not on your life.
