Packing' Advice!

Okay...I'm so into that "I need to pack for the hospital phase". I know it's too early to really pack but I'm jonesin to at least start my lists of WHAT to pack. I'm lost here. I went into Essie's room today to put together her diaper bag...I couldn't even do that. What do we need? What kinds of clothes, accesorries, etc? Help mommies out there...what are the essentials I need??? I mean realistically she could come at any moment now and I want to at least have something to go off of! :)
