Belly Rubbing???

We went to run errands today. When we got home, I went to get Max out of his car seat. He had his shirt pulled up and asked me if he could rub his belly on the leaves. I had no clue what he was talking about, so I told him that sounded fun. He got out of the car and laid face down on the grass. I have never laughed so hard. By the time I got my camera out, he had flipped over and was rubbing his back on the grass.

He was so happy that I let him do this and thought it was so fun.
