very cool pool playandlearn!! My LO would love that!!

I currently have a small pool, about 1 foot high, it has soft edges, not a blowup kind, not a hard shell. I asked parent permission before setting it up and showed them what it looked like. I still am very cautious and only use it with the kids when my husband is home to an extra pair of hands.
I would like to switch to a smaller hard shell pool and dump it every night. The sprinkler is also a good idea, but my patio deck takes up most of my yard, and i am worried about running kids slipping and cutting their head open on the wood patio or something.
