Cardboard box fun!

Whenever Little Brother's diaper boxes are in the house, Big Brother finds something fun to do with the box. He's turned boxes into a ramp for his cars by leaning it against the sofa; he's used them as a bed for his teddy bear, he's carried things around in them, but by far the most fun part is getting INSIDE! There are so many fun things for kids to do with boxes...

A few ideas:

• Use it as a ramp or a garage for cars or trains
• Turn it into a vehicle! 
• Build an elaborate cardboard box house
• Cut holes in it and make a shape sorter
• Pretend it's a mailbox
• Spend two hours on Pinterest browsing through "cardboard box ideas"  :)
