It's "Happy Birthday Dirty Bertie" day on ReadItDaddy today, and along with the children's picture books there's a range of early chapter readers featuring the boy with a billion dirty habits, Dirty Bertie himself.

The range now comprises 100 books covering a wide range of stomach-churning topics such as "Pants", "Bogeys", "Loo!", "Fleas!", "Germs!" and a whole host of other subjects dear to our favourite little flatulent fellah's heart.

We dipped into a few titles that Little Tiger Press were kind enough to send through for review - and though they're pitched at children slightly older than Charlotte (let's face it, grim and gross subjects NEVER get old for kids!) they're brilliantly written by the talented fella behind CITV's "Horrid Henry" series, Alan Macdonald.

With original illustrations peppered throughout the books by Dirty Bertie's creator, David Roberts, there's a whole host of giggles and guffaws to be had. The range is very reasonably priced so it won't wear too much of a hole in your pocket either!

Happy Birthday Bertie! Long may your nose be picked!

We're celebrating 10 years of David Roberts' stinky little lad Dirty Bertie on ReadItDaddy today. So what did Bertie get up to next after his previous dog-licking plant-watering antics?

How can we put it delicately? Trouser trumps? Bottom fluffs? Tummy squeaks?

Whatever you like to call them, trumps are trumps and in "Pooh, is that you Bertie?" we find out that little Bertie is a lad with a big wind problem.

"He lets off at the dentist
He lets off during tea
He lets off in a wendy house
With wild abandoned glee!"

As Bertie quite rightly points out, he's not the only one floating air biscuits at home. Mum covers hers with a polite cough. Dad sneaks them out when he thinks no one's listening and Gran? Gran blames the cat!!

This fart-tastic book comes complete with buttons to press at each point in the story, to treat everyone in the family to a wide selection of genuine bronx cheers (we've completely run out of trump analogies now I'm afraid!)

Funny and fwoofy, if you have a trump-obsessed little one at home they'll be in tears of laughter over this.

Charlotte's best bit: Big Sister's rather musical bottom burps

Daddy's favourite bit: Mum's polite trouser cough-cover (ahem hem!)
