Food
Cake marked with a "B", Hot Cross Buns, Cottage Cheese. For drinks I just used a fun color of Kool-Aid.

Decorations:
Use 2 stuffed dolls for Jack & Jill and set them next to a pail, which held the utensils. Another stuffed doll sat next to the cottage cheese and a plastic spider (Little Miss Muffet). Use a cute, girlish box filled with sugar and spices and a blue basket filled with plastic snakes and other boy things. Also boile an egg and "dress" it like Humpty Dumpty and sat it on the table.

Games:

Baby Bunting
If you have a computer make a sheet with a picture of Humpty dumpty on top and the guests had to unscramble various baby related words. Have a time race to see who could diaper and then swaddle a baby in a blanket the fastest.

Baby Animal Game
Compile a list of proper names of baby animals, like fawn, gosling, kid, etc... Use a dictionary or a kids book; they usually have the oddest ones. And the odder the better! Make a list of 15 to 20 names, and the guests have to name who the mom is like goose, deer, goat, etc... whoever has the most correct names wins!
