I am interested in learning piano myself having just gotten one for my kid. Did you learn it by yourself? If so any resources you can point in my direction? Thanks!
I'm sure Alfred and Faber have books for kids. Check reddit and amazon. But you won't go wrong with books from either probably.
To accompany the books, there are videos where people go over the pieces from the books as a piano teacher. I recommend this guy: https://www.youtube.com/watch?v=e4gizue_ULg&list=PL8hZtgRyL9..., but just search the book name + piece name
Lastly since you're both learning, look into duet books and utilize the split mode on your piano
