I got this out of the library for my 2.5 yr old a couple of weeks ago and he's demanded it every night since. I've logged on to amazon today to buy a copy as we have to return the library's one. It's a funny story about a little dinosaur who uses every excuse not to go to bed - he's hungry, he has a tummy ache, his bed is itchy, he complains that his sister is allowed to stay up late, nobody loves him, his friend never has to go to bed. I enjoy reading it because the characters and turns of phrase are very realistic and recognisable and also very funny, my son knows most of it off by heart and joins in, and my older daughter also listens in and finds it funny. Perhaps the only slight downside is that my son gets quite excited listening to it, so it's not very calming for night time, but otherwise highly recommended for 2 to 4 year olds.
