Quoting momma melissa85:" Dang, I can't go all out like that plus it will be winter and cold. I don't even know 300 people lol"
We're not rich or anything, we just saved a really long time to do it and knew that it was something we wanted to do. We both have HUGE families and didn't want to leave anyone out, especially since we don't see a lot of our family members very often. I have 12 sets of aunts and uncles if you include step relatives and DH has 6 (and almost all of my cousins have 2-3 children).
Edit: It's also at a better time, in mid-March. I really don't know what we'll be doing for this kiddo, especially with the weather. It isn't uncommon for us to have several feet of snow and it's not really like we could plan something too far in advance because of it.
