The first book had stuff in it I felt a little uncomfortable reading to them. Hagrids drinking for instance and all the “kill him” from Voldemort in front of the mirror of erised… but you gotta learn about death at some point and they’re already aware of it because of great grandparents passing away in the last year/few years. I read a chapter a night at the moment, but could space it out a bit more as we get deeper into the series. Or we could take a break and switch to another series when it starts to get really dark.
