I bought a baby pool for cooper and he tried to swim in it, however the water was only about 6" high. I decided to go to Walmart and buy one of those rubber pools. It's 8' round and about 3' deep. The whole setup cost less than $50. He loved the pool so much, we had to put a little fence up for security purposes. Need I say more? Now, he sits and cries at the fence because he wants to go swimming so badly. Check out the video!
