Right Hand, Left Eye

[Zoomie]

I as well am right handed and left eye dominant, I disagree with the assertion that you should teach your daughter to shoot right handed, because the only way to shoot right handed is by closing or squinting her left (dominant) eye. This will result in it being impossible to teach her to shoot both eyes open. Luckily I was taught to shoot left handed once my father found out I was left eye dominant, and I have been glad of that fact ever since. Another interesting fact is that I find it almost impossible to shoot a rifle with iron sights right handed, but find it much less difficult to shoot a rifle with 1x optics (eotech and aimpoint for example). I guarantee you that if she has not formed a habit of shooting right handed she will find it much easier and less frustrating to learn to shoot left handed.

Right handed left eye dominant here as well. I usually use the squint method. Half close my left eye to get sight picture.
try this, place a piece of scotch tape over the left lens of her shooting glasses, she does wear them when target shooting right? The image willbe blurry enough that her right eye will take over.

That is pretty much the technique that our coach used on my cousin a couple of weeks ago when we were shooting five-stand. She was wearing sunglasses, and he asked her to put her thumb on the lens directly in front of her eye. He placed a square of electrical tape on the spot which let her use her peripheral vision from that eye but forced the right eye to take over. She nailed the next clay.
