S.S.
i have a 4 & 6 yo. I haven't put them in anything yet because i want to make sure that they are going to like what they get into. i don't want to spend the money on registration, and everything that goes with it if they aren't going to like it or show interest in it. the only way to know though if they DO like a sport is to put them in each one until they know that they do like it. so instead of breaking the bank (we're a one income family) i'm going to wait until mine are older and then they can decide what they want to do. right now mine say they don't want to do any of that stuff. i take them outside and kick around a ball and they play on the swingset and ride their bikes and play in the bounce house so they get a lot of exercise.
edited: if you do want to put them in something now check out your county website a lot of times they have cheap sports that kids can play thru them.
