My kids never wanted to do it and I never forced them too.
One year Wal-Mart was doing the whole get your picture with Santa but you had to use your own personal device for a pic if you wanted. They took a picture but you didn't get to keep it. Yes I blew up in the store over it because it made no sense whatsoever for them to keep a picture of my child.
Yep .... under my close scrutiny.
Funny how we tell kids - Stranger Danger...and then we go and encourage them to sit on Santa's knee....
And some kids cry, too...
I never had that problem, my kids would NOT sit on Santa's lap. lol
The kid in the pic looks like Sunny.
