Makenna is determined to get in the fridge

Last week we had to buy a lock to go on the refrigerator due to Kenna would not stay out of it. All day she would go get whatever she wanted out and thought that she had to have it. So we bought a lock and put it on except for the older kids forgeting to lock it back it has worked until I was doing laundry today Kenna asked for a pickle I told her when I finished folding the towels I will get her one lets say she has no patience I heard the kitchen chair being moved on the floor and came to find Kenna was unlocking the fridge and going to get her own pickle.
