Putting cups into the toy microwave oven

Over the past 2 days Pascale has been regularly taking play cups by the handles and putting them into the toy microwave oven. She started off putting other things in but they didn't fit / didn't let her close the door. She has arrived at 2 cups side by side (not on top of each other). sometimes there is a moment when she is holding too many cups and can't close the door. Repetition about 6 times then she does something else.
