Baby Wearing Grandpas!

I saw a man today walking down the street with a baby strapped to his front in an Ergo type carrier. Her/His little chubby legs dangling out. He was fully grey, looked like grandpa but this is Seattle, so it could have just as likely been dad too. Grandpa or Dad it got me thinking about when Jon and all the other babywearing dads become grandfathers. Seeing an older grandfatherly person walking around wearing a baby will become a more common sight.... and what a WONDERFUL sight it will be!
