We're in the same boat Mariah. I was going to wait a few more weeks for the warm weather to heat the water up a little bit. When we were taking swimming class, she would even get cold in the heated pool sometimes....so that's the only reason I worry.
We did order her a baby pool from One Step Ahead.
Li'l Squirt Baby Pool, Sprinkler and First Pool
I was going to try that as soon as it came in, since it's not a LOT of water...just her sitting in it. Let me know how it goes, although I bet it's been warmer in Portland than here!
