not enough hands

We recently purchased a toy dump truck for Tyler. The payload is full of oversized building blocks, which Tyler loves to dump out across the floor. He often keeps both hands full with a block in each, but here lies the dilemma. With a block in the left hand and a block in the right hand, how does he move the third block that sits at his feet. Well, when you are Tyler this is easy to solve. You bend down and try to grab the third block with you mouth!
