If you got a little more money to burn the Parker challenger is, IMO, the best kids bow out there. They also have a package deal that comes with a rest, sight, one piece quiver, string leeches, bow sling, peep, and four carbon arrows. They also have a "grow up with Parker" program for the original owner. For $50.00 they will upgrade the limbs and cam modules as she grows. It comes in 20 - 50 pounds and 23 - 27 inches.
Just bought this bow for my wife. "Grow up with Parker" is the reason.
