A pink and silver/gray penguin party.
Penguins are cute, just like Addison, and appropriate for a winter baby. Pink because she is a girl and silver/gray because it compliments the pink so nicely.

My favorite items aren't pictured. We had a silver snowflake basket with small stuffed penguins in it for each of the children to take home. We also had snowflakes hanging from the ceiling to give the impression it was snowing.
