I'm not sure if this is quite what you're looking for, but...
My older boys are always saying they're hungry. So dh and I are always getting snacks for them. Many many many times a day. We have bifold locks on our pantry doors because there are a lot of glass things in there, and they've caused problems in it before.
Last week I cleaned out a cabinet in the kitchen and filled canisters with snacks for them. I also put three small plates and mugs in there. That way, they can go in and get it whenever they want. They're totally loving it.
One thing I've noticed with our kids, is that whenever they start acting worse, we need to evaluate how much independence we're allowing them. As much as it didn't make sense to dh when I explained it (or me when I was rambling to him about it), I felt that maybe they were desiring more independence. So far it has worked. Sometimes it takes dh and I awhile of being frustrated with them before remembering to look at what new things they're doing and what they might be ready for though.
