@LaKeia 😥 Awwww ... I hate when I hear things like this. Its so important for all parents, sitters, teachers, Grandparents, spouses, nannies, exes, caregivers to be on the same page. Even something as simple as using the same terminology, commands and potty words so your toddler-in-training won't get confused. Here's a helpful video for you that explains explains the importance of everyone being on the same page and staying on a consistent routine and will help you navigate thru this! https://youtu.be/s2nkqKQGgkU Maybe you can explain to the other adults in a gentle way that will make them want to get on board!!
Be the bad guy and keep the kid home. I would tell her upfront next time you take her. "She is not wearing diapers anymore unless she is sleeping. If you cannot follow this, then she cannot come here"
