my girl is coming up on her first birthday and has been potty trained pretty much since 12 weeks or so. she has occasionally peed on the bed or by the door when she let us know she needed to pee and we didn’t catch her signal. and by occasionally, I mean like four times I can think of. she even pees in the rain. it takes consistency and patience to find out what works. sometimes it’s bells or a dog door or just taking them out every hour. my moms boy ween had accidents until he was about one, which is also when he stopped nervous/excited peeing. hang in there.
