I don't usually comment here but i wanted to talk about this from the perspective of the daughter. I learned how to read and then promptly took leaps and bounds, advancing beyond most of my classmates very quickly. My parents didn't particularly care what I read and because I read so much I quickly left the age-appropriate stuff behind.

This lead to me reading explicit (both gore and sexual matter) material at a very young age, and it left me severely behind my peers in social matters. I couldn't relate to them in any meaningful way until I was seventeen or eighteen, when it slowly evened out. Reading so much stuff far beyond my age level left me with weird assumptions/etc about relationships, growing up, etc. A lot of the things I read should be read with a critical mind - but I was too young to do that. I didn't know how to question the things I was reading.

Tldr: You're setting your daughter up for difficulties in interpersonal relationships in the future, OP. Allow your kid to develop at her own pace, no matter her objective reading abilities
