If the mom-to-be is a bookworm, write a fun quiz—from naming the pig in Charlotte's Web to finishing Dr. Seuss quotes. Via Devourer of Books.
Hide a miniature plastic baby inside one cupcake before you bake a batch (so it's totally random), then have guests decorate cupcakes. Mom-to-be chooses the winner, but the real winner is whoever eats the cupcake with the baby surprise inside (because she's next in line to get pregnant!). Via Beau Coup.
Write down a list of names of characters from different TV families (like The Brady Bunch, The Simpsons, Modern Family, and Parenthood) and have guests try to guess the correct show.
Have your guests write down as many songs as they can think of with "baby" in the title. For a fun twist, you could have the songs playing as the party soundtrack prior to playing the game without telling your guests and see if they notice.
This game is like Pictionary meets Telephone. Have everyone write a statement about the mom-to-be (or her bump), then fold over and pass to the next guest who must draw what the sentence said. This goes on and on as the sentence slowly changes and becomes sillier and sillier. Via The Red Headed Hostess.

Three words: baby shower bingo! Pass out printed bingo cards to guests as the mom-to-be opens her gifts.
Have each guest bring a baby picture of themselves, and then have everyone try to guess who each photo is.
