A.N.
I had this kind of problem with my daughter she was going on 3 yrs old and I just finally took her out of her diapers and out of pull ups and put her in the cloth training panties. After a few days she got tired of the whole thing and started wanting to go to the big potty. I went to Walmart and got one that fit in the top of a regular toilet. She had a few accidents but it worked . Well I hope that you find something that works. Good Luck.
