Water babies

DD and I will be starting water babies in the next month or so, and I have some questions for you mamas.

How do you wrangle rinsing off and changing you AND baby after class? It's not like there are cribs in the changing room. The floors and wet and the benches are deathtraps. Seriously stressing out about this one.

Did the chlorine bother their eyes or skin?

Did you or the other babies in your group wear a bathing suit over the swimming diaper?

For breastfed babies: What kind of non disposable diaper did you use, and did it actually stop the liquid poop from leaking out into the pool?
