We didn't do the Santa pic for the first Xmas - I wasn't comfortable placing my 2 month old in the hands of a stranger.
We did it last year, though, and my boy did great. His photo is fab.
We are going to do this years' on Friday. I am keeping my fingers crossed htat he does a good job again. I was always good for Santa, Easter Bunny, etc., but my sister was a huge bawler.
