It's always nice when you see your children work together toward a common goal.
There are many things that we are not ready for Vicki and George to use without supervision. Many of these things are kept up on shelves out of their reach. Due to the habit of climbing on anything and everything they can carry, push or drag where they need it I have removed all plastic bins, drawers and crates, all toys that can be used to stand on, and I make sure no folding tables are left up, no laundry baskets left lying around, etc. And, it seems to be working. It's probably been a whole week since I last had to take away something they had managed to get down on their own.
