I would definitely introduce a mini potty! Practice going together since she’s showing signs! No pressure though she’s still so young. I got my son a mini potty at 12m and he’s only used it once but he likes to sit on it while I go pee!
Absolutely I would. My daughter was trained by 19m we just took her lead. My boy was trained a lil over 2 but I didn’t mind washing the training undies he was using for a couple months prior to undies (or the cloth nappies he was using before that) I took my daughter to Vietnam at 18m and she was the only one her age and older, who was still in diapers. According to the aunties over there she was “too old to be in nappies”. They train their tots really young over there.
