So my 2 year old is pretty much potty trained. He pees and poops in his small potty & we’ve done 2 outings without diapers & he stayed dry the whole time. But he did tell me he had to pee one time while we were out so I brought him to the restroom but he was too scared to use the big potty. He didn’t have an accident but waited till we got home to go. I’m buying a portable potty seat for him so he can sit on the big pottys while we’re out. But I feel like he will still be scared... how do I get him to be comfortable on the larger potty? The little one we have looks just like the larger ones and even has the flushing sound. I let him flush the actual potty when we are cleaning his little potty as well.
