I just bought a new pill box, the one with the days of the week written on each small compartment. It has a button on either end - red to unlock the compartments and green to lock the compartments. As I was filling it and thinking about what a clever gadget it is, I stopped in my tracks and realized the reason I bought a new one was because Ben ripped open the other with his teeth. I just don't think the little button system will stop him from getting into this one.
That will be a job for some engineer, making something Ben-proof.
