My advice is to steer away from rifles that are designated as youth or ladies rifles. Manufacturers. Ultra light weight rifle recoil more than their full size counter parts. At that age, and probably for a few more years, it will be dad, uncle, mom, or papa toting the rifle in and out of the woods. Go for heavy, with some means to reduce the length of pull. One great example of this would be a ruger RPR, or other type rifle that has some weight to it, but can be adjusted short. Could also take the butt pad off of a youth length stock and fill the hollow stock with BBs. My Tikka T3 youth took almost 4 lbs of BBs from Tractor supply and it cost $10. Knocks the recoil way down.
