Sounds like she’s already off to a better start even before starting then! Hope you both have fun learning and sharing the love for music.
I didn’t even have a teacher, I just had a couple of books, and thought that was the only way to learn so I pushed myself to strain my hands and my head to figure it out because I really wanted to learn and it really fucked my hands up for decades leading to further and further problems with advancing. After over two decades I finally corrected my hand position and well, ergonomy and everything became so much easier. Problems I wouldn’t have had if I’d had proper teaching or even a proper instrument for my tiny hands. Carpal tunnel is no fun, especially when the number one thing you want to do is play. If only someone had told me the things I know now.
