We have started potty training our 25 month old.
Ann, Hi and welcome to the Toilet Teaching board.
Your DD could be going through a regression period. There are some posts in the folder below with ideas on how to move on after regression. You know your DD the best, if you feel that she needs a break then take a break, and follow her lead for a set amount of time, and set a date to restart potty training again. In my personal experience breaks did not interrupt the training process. Please keep us updated on your DD progress.
