A few games that we played at the last few showers that I went to:1. Let everyone "estimate" how many sheets of toilet paper it will take to get around your sister's tummy. If she wouldn't be offended by this!2. Put samples of baby food out and have people taste them and guess what they are.3. Put a variety of baby items on a tray. Let everyone view them for like thirty seconds and then cover the tray or take it away. Let everyone write down all of the things that they remember.I hope that these help. Good luck planning! There are also tons of free websites that have printables and games that you could play with ideas for favors, etc. For example,
