The other day little man was playing on the floor with a golf ball.  He happily chatted to himself, repeating "ball" over and over again.  Then, suddenly, he turned and looked at me with the funniest face.  He crawled over to where I was sitting, with his lips puckered, breathing heavily through his nose.  He looked so funny!  I have no idea why he did it, but I made sure to take pictures.  :)
