C.D.
When we were new with potty training, we did a pull-up while out for fear of dealing with an accident while out and unprepared and he never regressed. It wasn't a big deal to him...kind of like a diaper at night, it's just what we did "just in case" so he went along with it. Then I stopped when he was completely trustworthy not to have accidents. I too would do a pull-up and then just periodically bring him to the potty and ask him to go (if he goes on command) with the goal of keeping the pull-up dry and not having an emergency run to the potty.
