Aaron has finally learned how to climb stairs. However, he cannot climb down them, and proved that (as well as the laws of gravity) by falling down six or seven of them. He’s fine, with two knots on his forehead and a sore tongue from biting it.
So, my question is this: Is there a way to safely block off the stairs? Airman put a baby gate across the stairs, but the bottom two don’t have a second wall, so a gate won’t work.
