I just did a shower for my daughter. Two of the biggest hits were:
Ewww! What's in that Diaper? Take 10 diapers and smear 10 kinds of candy in them. You can melt, smear, smash, and form various candy. It's pretty funny watching people open the little diapers to see a huge mess inside. I simply labeled each diaper with a 1 - 10.
Feed the Baby: This one can get messy. I draped a plastic table cloth over the laps of everyone, and put a plastic bag over their clothes (tear a place for the head and arms.) One person was the mom the other was the baby. Facing each other, the mom was blindfolded, baby had to say, "ma ma, ma ma." Each person has a small jar of baby food. I was nice and got plums. You wouldn't have to be so nice. The blindfolded mom had to feed the baby the jar of baby food with a baby sized spoon. I had three teams rather than everyone. The first team to finish the baby food was the winner. It was a blast to watch! Oh yea...don't forget making the babies wear bibs!
