Parent of two kids that have used swim diapers. I would be very surprised if those diapers were even 10% effective. Out of the pool they're basically 0% effective.

And yes, I've read the instructions, and spoken to the folks who run the pool.

Mostly I think they're just there to keep the poop in long enough to get the kid out of the pool.

That is exactly what the swim diapers are for!

Are you suggesting that perhaps some people think it is all right to leave their kid in the pool with a swim diaper full of excrement?

Sure, but it's not always obvious when a kid wearing a swim diaper poops. And they don't always tell you. Especially if they know it means they have to get out of the pool to change the diaper.

Swim diapers basically keep the _turds_ stationary. Water will still chew away at it and disperse poop everywhere, so its basically run out of the water when an "accident" happens. Still better than solid poop floating around I guess, but also, potentially, really nasty.

And this is a dead giveaway you're not a parent, or have never dealt with swim diapers :)

Swim diapers are designed to simply make sure the poop and the kid are in the same general area and that it's easy to remove them from the water as a self contained unit. It will still absolutely contaminate the water in some way, there's no escaping it.

Or, rather, there is a lot escaping it. :)

Poop can still leak out of swim diapers. After going to swim lessons with my daughter and a dozen other 6-month-olds at the local YMCA, I understand why it is so heavily chlorinated.

Dark secret - swim diapers don't hold everything in.

I got a staff infection from the pool at our apartment when I was in middle school. Looking back, that apartment complex was a real dump.

I wish they would ban swim diapers altogether. You never know what's in there, there probably is something, if the parents see the necessity. Just ban child and parent for a month if they can't hold it and spoil the pool for everyone.

So how exactly do you propose telling a 1 or 2 year old not to poop in a pool?

Children who do not have proper bowel control yet are out of place in the public pool. Why should people have to put up with someone else's faeces? It's not hygienic.

I agree with you, but more importantly, I think I'm done with pools after reading the comments today.

You’ve been swimming in pools your entire life. Somehow you are still alive. Maybe it is way less of a deal than it actually seems.

When I grew up they always had a separate pool for babies.

potty training!
