J.,
Do you have a cat? If so, (or not) try to get a hold of the plastic container that the cat liter comes in, the top will close tightly on it and the little one can't get into it without your help. Or if you wanted, you could go to Wal Mart and get a container that has a tight closing lid. You older one would have to also have your help opening either of them, so you would know "where" the toys are and they can be neatly put away and tightly "locked" up so the little one can't play without you knowing it. Good luck!
