piper in the kitchen

Piper loves emptying out the lazy susan cabinet in the kitchen. i'm afraid to put a child lock on it because then there is a greater likelihood that she will pinch her fingers in it because it is really heavy. but some days it seems like she spends all day coming up with schemes on how to break into the kitchen without me noticing so she can get back to her very important work of emptying out this cabinet. as you'll see, she's pretty neat about it. but what would be neater is if she'd leave the stuff in the cabinet (or at least put it back when she's done).
