Upon arrival, give each guest a diaper or, if you'd prefer, a folded paper napkin and a safety pin. Make sure that they secure the diaper to their shirt with the safety pin. All diapers are clean except for one that has some chocolate inside it. After everyone arrives announce it's time to find out who has the dirty diaper. Before each person opens the diaper ask them to tell a little bit about who they are and how they know the mom-to-be. The guest with the "Dirty Diaper" receives a prize.

Once all of your guests have arrived, have everyone sit in a circle. Ask everyone to pretend they were going on a weekend camping trip and they need to take as much or as little toilet paper as they would require. Pass around a roll of toilet paper. Once everyone has tore off their sheets, tell them they have to say something about themselves for every sheet they have. For the ones who took a few this will be easy, but for the ones who took a lot they will have a lot of talking to do!

Before the party, ask your guests to write down something unique they did as a child such as an instrument they played or their favorite book. On a separate piece of paper, make a list with all of their details in one column and a blank column for the name to be filled in. You may want to make a separate column with names for guests who never met. each other for half an hour. Then spread the lists out and ask your guests to guess who did what. A name can only appear once on each sheet. The one who matches the most correct answers is the winner.
