My older two trained quickly and once they trained, they did not have accidents. I think total they had three accidents before they were fully trained. My youngest has been potty training for three weeks. She mostly alerts, but I also ask make sure she goes. We had a few poop accidents during the first week, but that is getting much better. But, we have had pee accidents. Some days there are no accidents and other times she uses the potty and then 30 min later she pees her pants.
I am torn if we need to take a step back. Is this "normal"? Is this expected? She just turned 2, if that matters.
