Baby proofing kitchen

My son is about to start crawling which means we need to start baby proofing the house, especially the kitchen cabinets. The problem is, my husband can't seem to shut a cabinet door or drawer to save his life. The dishwasher door: open all day, unless I close it. Tupperware drawer: open all day, unless I close it. Under sink cabinet door: open all day, unless I close it. Pantry door: open all day, unless I close it. You get the idea.

Anyone else have this problem and have any solutions or tips and tricks? TIA.

(Also, I know all about cabinet door locks, but they're useless if you don't actually shut the door after you open it.)
