The Baby Gate at the Bottom of the Stairs

I apologize if this is prosaic, but I am sick with my second cold in as many weeks. We have to keep the baby gate on the bottom of the stairs closed now. If I so much as turn my head, Claire will climb up seven steps. With me standing behind her she climbed up all of the stairs twice today. Sam climbed up once. Claire is more regularly standing up by herself without a wall or chair to pull up on. The babies are no longer taking their early morning nap. They sleep an extra hour instead. I think this means that the rest of their naps are less stable. My guess is that their afternoon nap will grow longer and more predictable. We'll see. Sam slept for almost three hours this afternoon. Claire slept for two and change. Coming soon.... the story of the unicorn and the dragon.
