For this game, you will need to ask each guest to bring a picture of themselves as babies.
Place all of the pictures on a counter or table with a note card below the picture with a number. Give each guest a 3×5 card and a pencil. Have each guest guess which picture belongs to each other guest.
Once everyone has guessed, reveal which goes with which picture. The guest who had the most correct guesses wins!
An excellent prize for this game would be a nice picture frame.
