While having a December baby wasn't in our plans (he was very early) and it was a difficult time of year to have a new baby, I have to say I'm loving the whole birthday party in December deal now :) We went with all RED and GREEN for a Christmas themed party.
Instead of party favors we did a red and green candy table where kids could fill bags to take home. My MIL brought cupcakes decorated with red Santa hats and green Christmas tress.
There are so many fun Christmas crafts out there for kids which is great because you're stuck inside for December birthdays. I found a gingerbread kit inexpensive at our grocery store with ready made cookies and packets for decorating (read: cheap & easy).
We also decorated clear Christmas balls with colored Epsom Salt. I saw a similar activity on the blog Play at Home Mom. We could have also filled the balls with the colored salt, but this was simpler for little kids (if you fill the balls with sand, glitter, beads, etc it makes a great grown-up gift too).

When we sung "Happy Birthday" Andrew was SO enchanted. He was so cute and wide-eyed. He really loved it.
He thought he was so funny, digging into the cupcake :0 He's still doing well with the potty training, but tends to have an accident per day. I'm not giving up though because it's getting progressively better and we've even made short trips out and he's keeping dry. Plus, it's saving me money on diapers! Haha!
