For this game, you need just a piece of paper and pencil for each guest (and a name for the baby!)
Each person should write the baby’s full name on a piece of paper. Set the timer for 3 minutes. Everyone makes as many words as possible from the letters in the baby’s name. The person who writes down the most words wins.
A good prize for this game might be a “word game” such as scrabble or boggle.
