Knocks, Mama!

This is what Caleb says when he wants to knock his fist against mine. He is so serious when he does it too. It's random times that he comes to me, offering his fist and says "knocks, mama...knocks". I was running the other day, pushing him in the jogging stroller, and he turned around to knock my fists about 10 times. It was so cute but not necessarily good timing for me. I'm huffing and puffing up the hill, wondering why I torture myself and how I got blessed with the genes that mandate regular exercise and my little cutie pie turns around and requests I knock his knuckles...again and again. I'm tired just typing about it.
