(*chuckle*) Tacky or not, I have been quite involved in the organization of the shower my best friend is putting together in a couple of weeks . . . she has been swamped with job search stuff and taking care of her son, so I put together the invitation and sent it out (under her name, of course!
). I also worked out the last-minute scheduling issues that cropped up, and may end up delegating some final details (since she lives out of state and is coming up just for the shower).
I think it is great to figure out what you need (i.e. casseroles vs. more "stuff") and give your friends an opportunity to give it to you; I think that ultimately, EVERYONE wants to help when there is a baby on the way, but they are often stymied by trying to figure out HOW.
P.S. When you put together invites for people to bring food, make sure you ask them to bring the recipe as well! That way if you get any particularly DELICIOUS dishes, you will know how to make them in the future!
