These are the most ridiculous royal baby PR tie-ins

This will be updated with more examples as we wait for the baby's arrival.

Cocktails

Because nothing says 'newborn baby' like alcohol. London bar The Rib Room is offering two limited-edition cocktails in honour of the royal baby: The Heir, named after Prince George and The Spare, named after the new baby. As they say in the press release, the drinks are "royally affordable" at just £15 each.

A personalised royal baby biscuit tin

Biscuiteers will provide their hand-illustrated collector tin featuring 16 vanilla-flavoured biscuits for just 43.50 of your hard-earned pounds. The collection features babygrow, rattle and rocking horse-shaped biscuits as well as a biscuit-shaped bottle of champagne with the label '2015'. That's only £2.70 a biscuit.

Only £949. Thank you, Made.com

Abandoned kittens

Will the royal baby be a boy or a girl? Battersea Dogs and Cats Home note that 60 per cent of newborn kittens at their London cattery have been male - making it a "sure thing" that the baby will also be a boy. No, we don't get the logic either. And while we might think the tie-in is ridiculous, it's definitely worth adopting an abandoned animal.

This confusingly-titled book

The First Photo of The Royal Baby is actually a children's book about the royal baby's first photo - and everyone in the palace trying to make them smile. As the publisher puts it: "This fun book will offer parents a chance to talk with children about their very own "first photo" experience. Plus, there is a lesson to be had..."
