Baby shower planning

Taylor

How do I plan for my baby shower when I can't get a solid guest count?? I have a bunch of people saying "they might come" but won't know basically until like the day of the shower. I have a bunch of for sure coming, but i need to start getting stuff for the shower (since it's September 23, so less than 2 weeks) but how do I get supplies and whatnot when I don't actually know how many people will be there?
