I went with baby Mickey as a generic theme but as we are coming closer to the party (a week away) we wish we would have done something different. He doesn't even watch Mickey Mouse or anything. It was just a generic theme that is simple and doesn't lean toward any preferences.

We stuck with the theme of her nursery cause I couldn't come up with something else since my daughter isn't into tv

I've seen "Winter ONEderland" and I think that is so cute for winter babies!
