I smeared baby food on diapers that looked really gross- and people had to guess what was in the diaper lol
That sounds really fun!
I did one where I had everyone bring a pic of themselves as a young child (under age 2 preferred). I had pre-printed a list of who was coming. Then put the pics on a piece of cardboard, each one lettered. Each person had to try to match the pic with the person. This was somewhat labour intensive but, was a lot of fun and a great get to know you! (if you do this one don't forget a black marker to cross off people who don't come....I had our party at home and just printed off the list when the picture board was done)
This is a really neat idea too.
A game that I played at a baby shower that was fun was when the organizers had a paper with a bunch of questions about the mom-to-be (what she was wearing, hairstyle, jewelry, etc.) and she left the room about half-way through the party and we had to try to answer the questions while she was out of the room. There were also questions like if she had picked out a name for the baby, if she knew if the baby was a boy or girl, etc.
I don't see anything wrong with doing a no-kids party, as long as you arent't offended if people who can't find sitters don't come. I've been to showers that were no-kids and I just found childcare if that was the case and I actually liked having an excuse to have some adult time away and catch up with friends/family that it would have been much harder to talk with if I was chasing a little one around.
