1st Birthday, already?!

I can't believe that Bug is going to be turning 1! Where has this year gone? I need to start planning the party. The food, drink, decorations are no problem. The task that seems to be daunting is the guest list. With Moo, it was easy...the playgroup. This time around I never really bonded with the other moms from the hospital, and don't have a separate playgroup for Bug. Many of the kids in Moo's playgroup are older siblings now. Do I invite those families? I just don't know!
Thanks!

ps a few of you have asked about my last post, yes...that is what happened.
