I'm convinced it's time to potty learn

Faith totally knows when she is going potty in her diaper, she often grabs at it, makes a funny face, squats behind the chair etc. She sometimes will even tell me after that she has "poopy". So far she hasn't gone in the potty yet, she did however run behind the recliner squat down and pee in her big girl pants, however i did not scold her just took her to the potty and told her "she isn't supposed to pee in her big girl panties". Today i am going shopping and need to find her more big girl panties, she only has 3 pair so we havn't really been able to try this full time yet. I am anticipating that she will catch on to the idea pretty quickly, we'll see. So far she's very interested in the wiping part, which is hilarious LOL
