Ginger cookies for Christmas

Mom:  Nathanael, smile for me.  I want to take a picture to remember our cookie-eating and tree-decorating.

 Mom: Um, okay, maybe try holding up the cookie?

 Mom:  Let's try that again.  Smile!

 Mom:  Maybe not so big this time?

I give up.  How did they get him to smile so well for the school pictures?!  I imagine cookies were not in their hands...
