I can't get my child potty trained. She is 2.3 years old. I leave her without diapers, she goes in pants. She understands that she shouldn't write on her pants so she doesn't write at all, she holds it. I can't leave this way and I wear disposable underwear. She writes in them, and again she only goes in pants for 2-3 hours. I ask her to sit on the toilet, she refuses. What should I do? ? I started potty training her when she was 1.5 years old. Unsuccessful.
