"Yay! Another Baby!" Party

We don't want or need a "shower".  If it's a boy, we'd replace anything that got too manky with our son.  If it's a girl, my mom already wants to pick up "32 outfits in each size - you only need to do laundry once per size, right?"  (She's joking.  Sort of. She's already made 2-3 wall hangings for a future granddaughter.  Long story.) 

We will want to celebrate, though.  I'll want to have friends over one last time before the sleepless months.

Come out for a last hurrah before our big hurrah?

Edit to add:  We regularly have my husband's co-workers/our mutual friends over for dinner for no reason other than we like to cook/entertain and they like to eat. Whenever someone from his work does the same, they make a flyer for it so everyone has the time and address.  There is usually a theme involved.  Murica, "dress up to drink beer on our couch!", best BBQ showdown, Persian new year, wine-tasting, "wheedle SGT X into an RPG", "Chief Y has never seen Labyrinth", "Let's try out the new fire pit!" "Make DH watch a sports game", etc.  It'd be along those lines.  "Last dinner before we disappear of the face of the earth for a few months."
