Hey there! I'm another Fort Hood/Killeen mom!
The only place I've found locally that sells cloth diapers and cloth diaper supplies is Gaia's Garden in Copperas Cove. It's on 212 S Main Street. They've got a variety of cloth diapers there and tons of information on what's available locally. There's also a Gaia's Garden playgroup organized by some of the people who used to be regulars there. There aren't any kids your daughter's age right now (that I know of), but there's a wide spread of ages. I think the Yahoo Group is listed as Gaia's Kids or Gaia's Garden Kids or something like that.
