The good: LO will be learning how to swim
The bad: I have to wear a bathing suit for the first time in ~5 years.

So LO is starting baby swim lessons next weekend (sidenote: back-to-back toddler swim classes in this pool... can you imagine how much urine is going to be in that water?)

He has little swim trunks with the underwear-ish lining, but I feel like if he poops, it is not gonna catch it all, so I 'm guessing we need a separate swim diaper. Can anyone recommend one?

It's indoor, so I figured he could just wear a swim diaper and little trunks over them. Or just the diaper? Do I need a rashguard? Anything else?

What did your LO wear for swim lessons?
