Hello girls, I tried to teach her to use the toilet independently and yesterday it worked, she pooped, so I'm thinking about starting now, can you please tell me what period of time I should count? And I'm teaching her while she holds onto the legs, not the toilet yet, I think she won't understand until then, in general, can you tell me how to start correctly ??‍♀️
