I have already made it clear to her in life that we do not damage books, have taken books away for a while if she tears them, and she very rarely tears book pages or defaces them.
Just been upstairs and found she has pulled the pages out of a book that I had as a kid, and that my mum;s brother also had as a kid. I have checked online, it is replaceable but I am very sad that she has done this, and also pretty annoyed. Fortunately none of the pages are torn - it's just that it's one of those books that were stitched together rather than glued, so it will look very ugly if I try to tape it back together again.
What is the best way to discipline/teach a lesson? Obv I also need to get over my issues and just put away the books that are special to me, i realise my error in letting her get to it in the first place!
