Hi I personally think it has all been done before. But since it will be both men and women and even though she is having a girl you can use the color theme of green, or/and yellow sort of pale, for games maybe you could do a Gerber baby food contest, Who Can Eat the Most Baby Food in the Shortest Time?, who can drink the fastest out of a bottle, who changes the babydoll fastest?, if there are not going to be alot of people give every couple or person a babydoll and have them act as if it were a real baby at the end of each game make sure to give someone their own special prize. Dont forget to add the men also. Good Luck and i hope my answer helps!!!
