Ashley's underwater swimming

We have been amazed and loved watching the kids enjoy our pool so much already.  Ashley has decided that she is going to swim "underwater." She is still wearing her swimmies but takes a big breath, that in itself is a hilarious thing to watch, and then puts her face in the water and swims.  All this with her goggles on.  So frequently we will hear her say "want to see some underwater swimming?"  We always say yes!  We are also working on trying to swim without her swimmies.  I get her to hold onto the wall and step just a little distance away and tell her to push off the wall and swim to me.  She tries but we will keep working on that.  Scott is continuing to spend more time underwater than above and Ryan is almost that way now.  He can even get diving rings off the very bottom of the pool at the deepest part-about 6 1/2 feet.
