Benedict's Crawling to dangerous places

Now that Benedict's able to sit on his own and crawl quite comfortably, we can't let him out of our sight. Clarissa has been promoted to 'warden' to ensure that he doesn't start to pull the wires of my aquarium. Christa has been given the task to ensure that the colour pencil broken ends do not litter the floor after she finishes her colouring. He has started to pick things up from the floor and everything he grapples with goes into his mouth. It's true that Grandma said that we need someone to follow him as long as he is crawling on the floor. Help!
