Dax has figured out how to get the child proof door knob cover off of his door- which is a serious bummer at 6 am every morning when he's already in bull-in-a-china-shop mode upstairs!
He typically barges straight into Ada's room and plays with her vet set (which I bought him an even cooler one, but he still prefers hers) and dress up clothes. It wakes her up, irritates her, and gets the day started on an annoying foot. He also never allows her to go in there for some down time at any point in the day- and I totally understand that need for a break.
So we got Ada a gate for her door- and she is so thrilled you'd think it was Christmas!!! She can operate it, Dax cannot.... Yet :)
