I think you are doing the perfect thing right now - give her small freedoms and see how she does. Control the area she has access to and then increase that slowly. I'm going through the exact same thing with my 8 month old right now. He's allowed to stay in the kitchen in I leave for short time spans - if it's more than an hour, he's in his pen. He's not yet allowed upstairs unaccompanied (that's where Mama's shoes are haha). Eventually he'll have free reign of the house (hopefully).
