Like HK, we were more worried about the movies than the books. We have yet to let our DD see the final movie although I now think that she could more than handle it she is now 8.5.
It has to be said that DD had to have her mother read the scarier parts aloud to her (LOL) the first time through (she was 6/7 at the time). She has now read/reread them >7 times to the point where the paperback set that Santa delivered is looking pretty ratty and dogeared.
The movies turned out to be a great incentive for her to stay in her room all night without 'getting scared' - I am fully OK with a kid that is scared knowing that they can go into their parents room at any time, DW not so much. When we told her that if she could stay in her room all night without nocturnal visits to us for a month then she could see the first HP movie it amazing to see just how goal orientated she can be. She counted the days down and never came out of her room all night for a month LOL
