Things are looking more like a sleepover than a baby shower. Stick with that vibe and order food to be delivered.
To see what I recommend,
Since you're in the home of the bedrest mama–to–be, the last thing you want to do is make a big mess. Of course you'll be there to tidy up after the soirée, but the guest of honor will probably be pretty wiped out and ready for some R&R.
Keep things clean and maintain order by calling up the expectant mama's favorite pizza place, sandwich shop, Greek taverna, or whatever her cravings dictate.
By ordering in, you're saving yourself oodles of time, lots of prepping and maybe even some money. As long as you supply the utensils, plates and napkins, your party will be set to go. And, forget the dishwasher — you just need a good old recycling bin to take care of those pizza boxes!
