The puritan in me says this is not something we should encourage, surely, toilet humour doesn't have a place in children's literature, does it? Then I remember my children's favourite TV show from the 1980s, the wolves, who farted and belched and made everyone, including me and Wendy, have hysterics. Toilet humour is harmless, and when it involved dinosaurs, there's no harm done, is there? This will make you laugh, and the illustrations are terrific, so what can go wrong? I'll put the puritan in me back in the sideboard and save it for something more worthy. This is brilliant!

Expect this naughty rhyming story to be a seasonal favourite

The book, which is very reminiscent of Dr Seuss . . . is a lovely life lesson and deliciously naughty toilet-humour that will have young readers squealing in delight

Great for little people

They have masterminded a work of genius.

A very, very silly book written by two members of pop band McFly, Tom Fletcher and Dougie Poynter. The story revolves around Danny – a very greedy boy who asks Father Christmas for too many presents. But Father Christmas decides enough is enough and instead gives Danny a huge Dinosaur which results in a very messy and smelly consequence. If your child liked Aliens in Underpants or The Story of the Little Mole, they will love this funny yet cautionary tale.

One of the funniest, and one of the most irreverant Christmas books out there. . . If you like your humour to be slightly scatological in nature, then The Dinosaur That Pooped Christmas will have children in fits of laughter (and a large amount of adults too). . . Brilliant!

Beautifully illustrated, really funny and rather smelly

[This] beautifully illustrated picture book contains a moving message about love, loss and learning to accept change
