Dc is 8, year 4. First discovered Harry Potter books two or three years ago (older sibling was a fan), but I didn't allow reading past the third book as "too grown up".
This year, I have relaxed my rule, and Dc has just finished the sixth book.
Now I'm not sure whether the 7th book is still a bit too grown up - Dc did have a bad dream about some of the HP characters last night, and is generally quite a sensitive soul. But maybe not allowing it makes it into a bigger deal, whereas reading it allows some resolution.
What do others think? Reasonable to ban the last book having come so far (and absolutely loved the previous books)?
