How do you deal with public restroom potty's while out? Today he peed on his clothes, my clothes, and the floor at B3! lol

I bought a folding seat for this but it failed. I don't want to remove his shoes and pant/undie leg to allow his to open his legs farther. I hate that he has to hold on to the seat, so gross. I am trying to teach him to hold "it" down, but doing that while holding him up is hard.

I did put a potty in the car, I had to....so much easier to have him sit to go before we enter a store than have to deal with a public restroom!

I hope he grows taller quick so I can just have him stand!

WDYD?
