So we made the big bed change. Not because we wanted too, but because the kids broke one of the legs of the crib. My Uncle Mike and Aunt Judy offered us a full size bed that they no longer needed. (Thanks so much you guys!) It has been fun (note sarcasm here) getting Beth to stay in her new bed, but things are going alright.
After Ryan and I put them down one night, we were sitting in our room talking. We heard some noise downstairs and found Beth reclined on the couch, with the TV on and her feet up. She had somehow slipped by us and was making herself comfortable.
