I remember when my daughter was starting out moving around and we just used to go to the park and try out different things, playing on grass and other softish textures where she could learn new things safely and i could feel like I was participating in some small way.  As she gets older you will find new things to experiment with and new places to find it which will help her to explore, be curious and investigate new things as she grows older.

I enrolled my son at the local YMCA's parent & child swim class when he was 6 months. It's a class that's offered year round in my area. It's a 6 week class (Saturdays for 45 mins). Then I enrolled him 2 more times until he was nearly 2. He became quite comfortable in the water but he stll needs a floaty. Now that he's 3, the Y starts formal swimming instructions (without the parent in the water). Before they are 3, the class is all with the parent and it's pretty much just play and learning to kick.

So just based on son's ability and YMCA's policy, 3 is pretty much the age to formally teach swimming. My twins are 14 months old now and we have yet to take them to a swimming class. I just can't figure out how to do it with the both of them. :-(

It's a lot of fun, check it out!
