I know we're grateful if they read anything at all etc etc, but there are some books which make me howl with misery at the thought of MY having to read and others which I just wish they wouldn't read.
For me: any of those fairy books, The Secret Seven and (from long ago) anything featuring that dog, Spot or that blimmin sheep Wooly who lives on that farm with Mrs Boot and her children.
for them: Captain Underpants, Horrid Henry - everybody is so darn nasty - and that one that's a bit like Captain Underpants but is about robots.
