With just over a week to go until the Duchess of Cambridge hits her due date, preparations for the new arrival at her Norfolk home, dubbed 'Fortress Anmer', have been heating up. Carole Middleton, the new arrival's grandmother, has become a permanent fixture at the country home, while in the nursery, nanny Maria Teresa Turrion Borrallo is preparing to welcome a second charge. But while much of the effort has focused on Prince George and making sure he doesn't feel left out, more still has gone in to giving the nursery a makeover. Scroll down for video . Preparation: The birth of Prince George's new brother or sister is expected to happen later this week . Overseen by Mrs Middleton, both the Anmer nursery and the one at Kensington Palace, have been given a Beatrix Potter theme. Fittings for both are thought have come from luxury children's furniture emporium, Dragons of Knightsbridge, where Moses baskets start at £75. But in a curious twist, it is understood that Kate had several pots of pink paint delivered to Anmer Hall from the Annie Sloane store a couple of weeks ago. In a move certain to invite further speculation over the sex of the baby, among colours chosen was Henrietta, which is described as a 'beautiful rich complex pink with a hint of lilac.' Another was Antoinette, a 'soft pale pink with a hint of brown' that is redolent of 'old-fashioned roses and the colour of old plaster' and the third, Emile, a 'warm soft aubergine colour with pink and red undertones'. Home: The new baby will spend its first few weeks at his or her parents' Norfolk home, Anmer Hall . London pad: The new arrival will also have the run of a second nursery at Kensington Palace . Each pot comes with a price tag fit for a royal, with just one litre of the paint costing £18.95. Kensington Palace refused to comment on the story saying that they could neither 'confirm' nor 'deny' that the couple had plans to paint the nursery. Echoing the palace's line, a spokesman for Annie Sloan said the company could not ‘confirm or deny’ that it had supplied paints to Anmer Hall. Nonetheless, a pink nursery appears more likely than the African-themed one hinted at by Prince William in an interview with CNN. 'I'll have toy elephants and rhinos around the room,' he joked. 'We'll cover it in lots of bushes and things like that, make him grow up as if he's in the bush.' Boy or girl? Kate's pink coat and pink paints have fuelled speculation over the new baby's sex . Compelling: Annie Sloan has  supplied three feminine paint samples to Anmer Hall . Whatever the nursery's eventual colour, more work still has gone in to turning Anmer Hall into a secluded property where Prince George - and his new sibling - can enjoy a relatively normal childhood. The refurbishment, which has taken two years and cost £1.5 million, has seen new security features added to the ten bedroom property which also has a swimming pool, tennis court and extensive grounds. As part of the costly renovations – which also included installing a new roof, a state-of-the-art kitchen and a conservatory – William had the driveway to the property, which used to belong to his close friends the Van Cutsem family, rerouted so that anyone accessing the property is shielded by trees. More money has been spent on filling the royal nursery and with both William and Kate known to have traditional tastes, it's safe to say that that extends to the toy box. Prince George has been cutting his teeth on old-fashioned wooden toys, while his reading material includes the Curious George books - the first of which was published in the 1950s. Toys for the new baby will be no exception and are likely to have a homespun wholesome feel much like this £34 Anne-Claire Petit Crochet Lamb Music Box. Prepared: The Duke and Duchess of Cambridge also have plenty of pieces left over from Prince George . Traditional: The Duke and Duchess of Cambridge have traditional tastes and prefer old-fashioned toys . One for George: The couple were presented with a Dorothy and Theodore box when George was born . Tally ho! Both royal children are likely to start riding as soon as they are big enough, much like the Queen . Kate, who has made no secret of her liking for traditional fittings such as Moses baskets, is also likely to follow suit when it comes to toy boxes. Indeed, the couple already own one, having been gifted a £360 Dorothy and Theodore toy box by 10 Downing Street following Prince George's birth. Another Dorothy and Theodore piece likely to feature in the royal nursery is the company's £550 rosewood rocking horse. William is a keen horseman and both Prince George and the new baby will have no shortage of steeds to choose from when they get a bit bigger. Indeed, the royal baby's great-grandmother, the Queen, has been riding since the age of four when she was presented with a Shetland pony named Peggy.
The Duchess of Cambridge is due to give birth on the 25th April . New arrival will have the use of two nurseries, both shared with George . One at Anmer Hall in Norfolk and a second at Kensington Palace . Duchess is thought to have ordered £18.95 pots of pink paint .
