How many people did you have at your kid's first birthday party? I'm sending out almost 50 invites and for sure out of those 30 will come (that includes the kids) because it's us and 3 families that always comes to family events.

I invited old friends that has kids around same age so that she can start making friends early (she loves playing with others), I invited my 4 favorite teachers from the past, and family.
