This is a book for little ones which, as the title suggests, has the message that 'my mum is the best'. It's very simple with little text, and lots of cute pictures of the mummy hippo and her baby. My son loves books but really wasn't taken by this one. I don't think he could really relate to it so has only wanted to read it once or twice. There's nothing wrong with it, it's just not very exciting. A nice message though.
