Pajama Problems

Eliza has complained the last few mornings that she couldn't open the refrigerator. (She usually gets the juice out in the morning so I can fill her cup.)
At first, I was annoyed - was she just being lazy or silly? This morning, I finally asked WHY she couldn't open the refrigerator. She clearly explained to me that every time she tried to pull on the door, her feet slipped. It has been cold the last several nights, and apparently, pajamas with feet and wood floors make it very hard for two-year-olds to open the refrigerator.
