Anna & I went to the big pool today with playgroup (we are meeting there once a week in addition to the regular playgroup). She was a little skeptical at first, but when we got out after about 15 minutes (there is a mandatory 10-minute break each hour—I'm not sure why) she wanted to get back in. I packed a pretty full diaper bag but next time I need to bring with us: a little beach ball, a trash bag, and possibly a contraption for Anna to float in to give my back a break. She wasn't into standing or sitting in the water (1 ft deep). That might change though after swimming lessons and when we go to a different pool with an even shallower depth.
I have some video to post (not from the pool though!), just need to sort through it and edit.
