While a Crocket's "ok", and "great" for her, since it come in pink (I got my Grandson a Chipmunk), in reality they may be a bit much for a small child to cock (the bolt's cocking knob must be pulled back against the mainspring pressure).
Since YOU'RE the adult, and small kids don't know any better, why not start her on a Ruger 10/22 (or other) auto-ejecting single shot rifle ?
If you never/ever remove the magazine in the child's presence, they'll have no way to know it's actually a repeater - and dutifly single-load each shot into the chamber.
Of course, you'll hear about the charade, once the child's old enough to find out - but by then, they should have already had several years of safe shooting under their belt.
