I don't think you need to go all out and have something huge, but you should definitely do something special for you guys. We had our close family and friends over (there were only 4 kids and they included 2, 3 year olds, a 10 year old, and a 12 year old) and the party turned out great. My husband and I are big football people and since we like 2 different teams and since we had twins, we did it as a Steelers/Falcons party. Everything turned out great! Everyone wore jerseys and it was laid back and fun! The boys were a little overwhelmed, but loved having a lot of people around to hold and baby them and they tried opening presents. They didn't dig into their cakes like we thought they would because they don't like getting messy and I had never given them anything like cake (no juice, no sweets, just fruit, veggies, and meat). So they didn't know how to act. We eventually had to feed them some, but we didn't give them a lot because a lot of babies can't handle a ton of icing, especially if they aren't used to it (just a warning, you don't wnat a baby puking up icing!). If you do decide to have a birthday party, you can get free cakes for them to dig into at wal-mart, weis, sam's, giant, etc. Just call around ot local stores and find out. Some require a birth certificate, some require that you buy a regular cake there, etc. It's definitely worth it to have a party, but don't worry about having a huge bash that they won't even understand!
