My daughter got the lovely Kipper's Birthday by Mick Inkpen as a present. Not only is it a lovely book, but it comes with a lovely introduction by the author in which he says:
"What any author wants is for his books to become dog-eared and familiar. I've been lucky enough that my very young readers are particularly adept at giving their books doggy ears in no time at all."
Which is a lovely thing to write as I had been holding back the paper books in favour of board ones so that they don't get too ripped and creased. Now I realise how silly that is.
