Recommendations for washable swim nappies for an autistic five-year-old

[TattyBluebell]

Hello!
I haven't posted on here before so I don't know if I'm in the right place.
My five year old grandson has autism and isn't toilet trained yet.
A friend of mine has said that we could use their swimming pool over the summer.
I'm just looking for recommendations of swimming pants/pull ups to use for him. Are there washable types?
Obviously I don't want any little accidents in my friends pool!
Many thanks!

The splashabout swim shorts are good. We use them for our daughter. Just make sure they are really snug fitting.

OK, thank you very much. 😊
I'll have a look at those. I'll be ordering online so won't be able to try them on him first. Are their sizings accurate?

Check your grandsons measurements carefully as the ages aren’t what to go by. If you size up they will leak. My daughter is 16 and fits the largest child size. She is tiny mind! The measurements are on their website

If Splash About shorts dont work for DC, you could look at Kes-Vir.

If you don’t find a reuseable product that works for you/DGS (some people don’t. We haven’t.), you could look at Swimmate’s disposable swim nappies. Some people who use them let them dry and reuse them if they haven’t been soiled.

Thank you so much for your replies. I will certainly be checking those out.
Thank you!
