This is a fun game and quite amusing!
Cut up about 20 small slips of paper, and write one baby item on each. Divide the guests into two teams. A member from the first team randomly selects one slip of paper and takes it back to her team to read. Then the guest who drew the slip has three minutes to mold playdough into the shape of the item listed on her piece of paper while the second team constantly tries to guess what the item is. Once the second team has correctly guessed the item, the time is noted on their score sheet. Then it is the second teams turn. (This is like Charades but laughing is allowed!)
