Christmas Gift for my Sister In Law To Be?

I've already started shopping for Christmas! My boyfriends' brothers (John) wife (Judy) is about 25 or 26 years old. They have a 2 year old boy (Evan) together. I already have Evans, and Johns!... But I have NO clue what to get Judy! It should be easy, because I'm 20, so, we're kinda in the same age group, but seriously! ANY ideas would be wonderful.. It can be either something to get from a store, or a website that I could order something from.. Anything! Just please, help me!
