King Charles III is said to never go anywhere without his childhood teddy, especially when he goes travelling. Everyone has their own creature comforts when they go travelling, and the Royal Family are no exception it seems.According to royal biographer Christopher Andersen, King Charles III takes his childhood teddy bear with him everywhere he goes.The author of The King: The Life of Charles III explained to Entertainment Tonight how strong the new monarch’s sentimental attachment was to his teddy, so much so that he would only allow one person to tend to his companion’s repairs, his childhood nanny, Mabel Anderson.He said: ‘He still travels with a childhood teddy bear. He’s had it since he was a very small child… The only person who’s been allowed to mend King Charles’ teddy bear is his childhood nanny, Mabel Anderson, who he remains very close to.’During his childhood, King Charles would only trust Mabel, or ‘Mispy’, as he called her, to tend to the repairs. She was even pulled out of retirement to look after the teddy bear.READ MORE: Zara Tindall stays in good shape by avoiding breakfast foods King Charles always travels with his teddy bear (Image: GETTY) King Charles treats his teddy bear like ‘his own child’ (Image: GETTY)The biographer even claimed King Charles went as far as treating his teddy “like his own child” all the way into adulthood.Christopher wrote in the book: ‘He was well into his 40s, and every time that teddy needed to be repaired, you would think it was his own child having major surgery.’His book also claimed the King’s aid, Michael Fawcett, looked after the bear, being instructed to know where it was at all times.As well as always travelling with his favourite childhood teddy, the new King must follow several other travel rules.DON’T MISS:’I was miserable’ – Fergie shares how she ‘lost close to 50 pounds’ [DIET]Zara and Mike Tindall left ‘beautiful’ £1.69m mansion [PROPERTY]Royal aides ‘fear’ The Crown could ruin Royal Family’s image worldwide [ROYAL] R] Mabel Anderson – King Charles’ childhood nanny (Image: GETTY)In the years running up to her death, the Queen appeared to relax this inhibiting travel rule for the Royal Family.A royal spokesman said in 2014: “While there is no official rule on this, it is something that the Queen has the final say on.”Prince William is now first in line to the throne and his children, Prince George, nine, Princess Charlotte, seven, and Prince Louis, four, are second, fourth and fifth in line respectively.While Prince Harry is only fifth in line to the throne, tradition dictates that he is not to fly with William. If something were to happen to Charles and William prior to George turning 18, Harry would be required to serve as King until the young Prince turned 18 and came of age.
