doesn’t listen!

anyone else’s 20 month old not listening to parents? well more so me. she will listen to her dad in a heartbeat but idk what it is about me that she doesn’t want to listen to..she jerks away from me.. she never listens when I tell her to stop or if I tell her to sit down..i have to say it loud and sometimes that doesn’t even work.. makes me seem like a bad parent bc it seems like i’m always yelling at her 😕 but that’s not the case she’s 1 and getting into everything.. anyone else going through this?
