OT: Baby Shower Games
The baby food game is always a hit. Buy baby food and take the labels off and then pass the jars around and have people taste them then write down what they think it is and the person with the most correct gets a prize
Word scrabble, Take words (related to baby items) and mix up the words and within a time frame they have to unscrabble the words, winner is who has the most words correct.
Questions about mom, Write down a bunch of questions about mom and see who gets the most correct and that person wins the prize (favorit color, eye color, shoes she wearing, year she graduated)
Price game; buy things mom will need when baby comes and have people write down the price and whoever is closet to the actual price wins. (diapers, wipes, shampoo, finger nail clipper, socks, formula)
Hope that helps or gives you a few ideas
Take large safety pins fold over pieces of pink and blue cloth to look like diapers. Every guest gets one "diaper". If someone hears you say the word baby that person gets to take your diaper. The person at the end of the shower or after a certain amount of time wins the prize. I know there are some good sites with baby shower games. There is one also with candy bars but don't remember what it is.
