So today Stinkerbell figured out how to do this:
She was able to climb over our rigged barricade and out of confinement. Thus, we have resorted to Plan B: ship her off. Just kidding! I took down the barricade and baby-proofed the rest of the downstairs. Hopefully this will satisfy her desire to explore beyond the livingroom long enough that I won’t have to hover over her saying “no” thousands of times a day (instead of the usual 100.) Also, I still swear she is part monkey. She climbs EVERYTHING!
