Can you reccomend me a song for a slide show?

Okay, I know this isn't in the right category per say, but this is where all the mommies and daddies hang out and I want your opinions!

In 2 months my oldest will be two, in 3 months my youngest will be 1. I am doing slide shows for their birthdays. I need music to set it to. I did one for my oldest sons first year and used Bob Dylan's "Forever Young". I'm thinking about using Cat Steven's "If You Want To Sing Out" for him this year, but haven't made up my mind.

I'd like songs that aren't *too* sappy, and something relevant to children/babies, growing, or individuality. I'd prefer no country, but I'm flexible. They are both boys! Thanks!!
