Playing in the cabinet

I made the mistake of letting Kendall get into the Tupperware once to keep her occupied while I was cooking and now she likes to play in there. Today she took EVERYTHING out and climbed in. I was not paying attention to her and I noticed she was sounding really frustrated and starting to scream. She had locked herself in the cabinet bc she closed it in on herself and the child lock would not let her get back out!!! I had to snap a picture before I set her free.
