ha ha 5LM - the thing that I realized is I am still in control LOL. I control what I put in it and how much and then how much of a mess it will make.

As for strapping them in a booster seat. nope I don't own any. All kids sit at a child sized table with child sized chairs except for any that require a high chair. Those that require a high chair will not be participating in the sensory bin because the items inside will be a choking hazard (and they would make a mess lol). The kids know they can't leave the table until I say so and when they do it is straight to the sink so I can wash their hands.
