My brother & SIL are taking care of the ornament - they got DD beautiful one with her name and the year on it for her first Christmas. Unfortunately she broke it last week so they're getting her a replacement this year and one for DS. Every year from Snapfish I get a little heart shaped one with a photo of DD on it so this year there'll be two, but I get them early and they just go on the tree.

I like the sock rattle idea, I haven't seen those before! Something he can wear/use while quite young
And MD you've reminded me I want to get him a decent play centre thing, one of those things he can sit in with toys around it. We borrowed one for DD and it was so handy when I needed to get stuff done and she could sit there and play.
