Had the same issues with my 4 years old. Eventhough she can say that she wants to pee or poop, she still refuse potty. She will wear diaper still. We try not to force her but read books on toilet trainings and picture of similar age kids using potty to explain. Having said that we try to toilet train during her holiday period. Looking forward to NO DIAPER as of next year.
Have you tried peeing in front of her on the toilet seat? When I was struggling with my daughter being potty trained I tried this she saw me a few times n started on her own .. they just need to be assured
Why don’t you get her a baby toilet seat which you could easily use on the commode? And make trip to the loo fun.
