Swimming Slump

I got her this turtle pool/sandbox/play area last summer when she couldn't even sit up! I actually got it for a great deal, $4.99! I watched it all summer long come down in price, until finally they were running out to them. We've had it up in our room just filled with the balls for her to go in and play with, but when I filled it up with water today she wasn't so sure about this!

(If you click on the pictures it will enlarge them) Not sure what to do, she eventually picked up the balls from the pool and just kept throwing them back in. I kept asking her if she wanted to go in or get her feet wet, and would adamantly say, "NO". She did NOT want to go in.
In fact she did want to go in somewhere, but it was not the pool! Hopefully, we'll do better next time! I should mention she is in her new swimsuit Grandma, Grandpa, and Aunty Em got her! Thanks, it fits and looks great on her!
