I realize this thread is a few weeks old, but I was curious at how things were going with your left handed daughter.
I am left handed. I taught myself to crochet 10 years ago...right handed...because that is how the book read. I don't really move the crochet hook, I move the yarn.
Learning to knit was hard at first because I could not change how I hold the yarn. This site was a God-send for showing me the Continental method. Since I already was comfortable with holding the yarn in my left hand it came smoothly.
I would recommend the Continental method because she can control the yarn with her dominate left hand and still read "normal right-handed" patterns with out problems.
