FIRST, regardless of eye dominance, KEEP IT FUN FOR THE LITTLE ONE.....CHEAP OUT; CHASE HER OUT.....spend the money to capture, retain her interest. Milo-2 has great thoughts above. Moving, reactive targets give little one instant feedback and fun. They don't get excited in small groups. When I was a kid, I loved to shoot my little plastic green army men, but couldn't have cared less about a paper target grouping. Come to think of it, I haven't grown up much in that respect. HO-hum about paper groupings,, a necessary intro evil, but love to ring steel in the third zip code over. Without her continuing interest, eye dominance won't matter. Be sure the gun fits her or she will struggle getting a good sight picture......think moving, changing shadows, picture.....frustrating even for we old guys. Ill fitting rifles and cheap scopes are a major frustration source. Spend the money to allow success. . Having your little girl get interested, stay interested in shooting/hunting with you is a priceless gift. Invest in it; big ROI. Sadly, I've seen many guys cheap their GFs, kids out of shooting sports. Then, determine for sure her eye dominance. Then deal with that.
