Gates

DH and I have fairly different ideas about what D is and isn't allowed to do. When he is home with me I let him run around the house, but I go along with him to make sure he stays out of things he shouldn't be into. DH tries to blockade him into the living room so we can keep an eye on him. Dean at this point can climb over anything we use to blockade the living room with ease. This causes lots of "angst" between DH and I, particularly when I'm trying to cook dinner.
To solve one of the main problems of D going into our bathroom where all the cat stuff is DH brought home a gate, hoping that the cats could fit through but the kid could not. To help our old blind cat get in and out he set the gate about 5 inches above the ground.
Once it was all set up D and I went to check it out. At first he was MAD that he couldn't get into our room, but it took just a moment for him to lay flat on the floor, turn his head, and wiggle under the gate. Then he sat (on the far side of the gate) grinning at us. I haven't laughed so hard in a very long time!
