A royal author has claimed that The King was "longing to be hugged" by his mother Queen Elizabeth as a child and instead found comfort in his nannies.
Ingrid Seward also claimed that King Charles was very "sensitive" when he was younger.
It has been reported in the past that The Queen did not form a particularly close relationship with her children when, because she took on the huge role of Queen when she was just 26 years old.
She was also a part of a generation and class that routinely left the daily care of small children in the hands of household staff.
In past biographies, Charles has been quoted saying it was "inevitably the nursery staff" who taught him to play, witnessed his first steps, punished and rewarded him.

"I'll remind you that Princess Elizabeth only had time Charles until he was 4 years old before she became Queen.
"Then her children were taken away from her. Not literally, but mentally they were because she was so busy being the Queen.
"She was only 26, at the time it was such a man's world.

"Taking care of the children went on the back burner. But that was fairly normal for those aristocratic families in those days.
"They saw their children in the morning and then they saw them again in the evening.
Host Eamonn Holmes asked the biographer: "Was she his mum or was she the queen?"
Ingrid responded: "She was the queen, but in later life, she was his mum. It was really through his work with his Princes' trust, she thought he had done such a marvelous job with underprivileged children and the inner cities.
"He cares about the youth of this country in a way that makes her very proud. But it took him a while for her to show this to him.

She later added that King Charles's parenting style is slightly different and he has built a "close relationship" with his children.
She said: "Charles was very close to his children, especially Harry. William wanted to be with Mum, but Harry loved doing things with Charles.
"He loved going into the gardens at Highgrove and learning about plants. He loved the military, he loved horses. Charles was an indulgent father, but when his relationship with Diana broke down so badly, Diana's weapon was to take the children.
"Charles would organize to take them to Polo, and she'd take them shopping."
