Empty Milk Cartons

After Mady's lunch, I take her out of her high chair and let her stretch her legs while I warm up some milk.

Every time, she goes to the kitchen for empty cartons of milk and/or orange juice, and sometimes even bottles of coke. She grabs one in each hand and runs up and down the hallway and all through the house, as shown on the left.

I love this, I think it's hilarious. She enjoys it so much, I can't help but to smile every time I see her go into the kitchen and reach for the empty cartons...
