How do you toilet poo-train your toddler? She's toilet pee trained but I think poo train is a whole new boss level!

Plenty of patience and trial and error! Took me about two months before my Ger (2 year old then) to be comfortable to go to the potty to poo. I always ask her does she need to go potty when she have that wan to poo expression! But after a while, she feels that poo in diapers is disgusting too. She started going to poo in the potty on her own.
