My daughter is 2.3yrs old. She uses diaper only in the night and during the day is in her underpants. When she does her pee, she tells me to change her underpants. Same goes when she poops. She informs to change after she's done. My concern is to make her sit on the potty seat. She's scared to sit for pee or poop on the pot. Also she doesn't allow me to use the toilet. She sits on the pot to clean after the poop but is never ready to sit and poop. How can I convince her to sit as I have tried all means to convince her? I don't understand what is the fear about?
