Music Ideas

I am making a video of many of my kid's photos from the last few years for our parents Christmas gift. (Hopefully they don't check my blog, if you do, SURPRISE.) However, I need help choosing songs. If you were making a Christmas video of your kids, what songs would you use? Thanks for any help.

P.S. Thanks for all the input on Mason's hair. Looks like the majority thinks it should stay, and the majority wins so Mason will be keeping his locks for a little longer. (He likes his hair so it's probably good to keep it longer.)
