When we do multiple birthday parties with the kids, we try to make the actual birthday at home with just us. We have a few traditions. Almost always there are birthday donuts with a candle.
We had a low key day since Daniel was at school. The sun shined and we were outside almost the whole day. We'd done a last minute invite of a couple of friends for cupcakes, but they weren't able to come. (Mommy should have planned better, but I never told Gracie, so she wasn't disappointed.)
