This is more of a joke on the new mommy-to-be then an actual game, but well worth the photo op if the new mommy is a fun loving and easy going gal.
Draw a large baby boy on a paper and tape it to the wall. Tell everyone that the object of the game is to pin the diaper on the baby boy blindfolded. Everyone thinks this is a spin off on the ‘Pin the tale on the donkey’ game. However, this time round get the mother to be to go first. As soon as she is blindfolded, whip out a bunch of water guns and spray her with water. She’ll be shrieking for mercy before you know it but tell her with baby boys you have to be careful else you get sprayed!
