Quoting Mel_brown:" That's what my mom said.. The babies room is a animal/circus theme. But i wanted to do something different.."
Well, then I don't know what to tell you. The theme of the nursery as the theme of the shower is pretty much a standard as to my knowledge. My shower was in AZ. I have been to showers in CA and here in MT. We have all done them the same everywhere.
If you don't have an idea as to what theme you want, then maybe the animals/circus might be your best bet. Plus, when your guests get the invite, they typically go off the theme of the invite as a "special" gift and they don't always buy off your registry.
