Help 18 month old keeps taking off diaper

Holly

So my daughter is 18 months old and the past week maybe a few days more she keeps taking off her diaper and it won’t even barely have pee in it she only does it occasionally but it’s becoming more frequent she’s peed in the potty a few times but she’s not mentally ready I don’t think like she barely talks so she can’t tell me she has to potty so I’m wondering how can I get her to tell me she has to potty or just solve this problem in general I’m more than happy she’s seeming ready to potty train I just can’t figure out how to get her to communicate tia no rude comments pls
