Activities:
This needs to be done in advance. Write down all your guests’ names. Look up the meaning in a baby name book. (Some names are derived from another name, use that meaning.) I n one column list their names, and in another column list all the different meanings. Your guests have to guess whose name matches what meaning. (If a guest has an unusual name not found, list a corky character trait that person has. i.e. - Jazzton = likes to belch and fart on command.) Or you can use a funny physical description (i.e. - she walks around the office with a pen on each ear!) or character traits, instead of looking up the meaning. Make sure the descriptions aren't too harsh or embarrassing. You can get suggestions from other guests.

Games:

The Perfect Baby
Ask the guests the following questions – “According to the mother-to-be, her perfect baby would have …” For example, pretend the mother’s name is “Jane” and the father’s name is “John”. So one question would be: Who’s eyes would the mother to be like the baby have: Jane’s or John’s.” The person who guesses the mother’s-to-be most perfect baby, the one with the most correct wins.
