Queen Elizabeth lovingly stares at Prince Charles’ adorable face in a throwback photo.

In the snap, a young Queen is looking at her eldest son while Prince Charles’ eyes are closed. The two royals are grinning from ear to ear, and they also look very close in the picture.

The heir to the throne is also leaning towards his mom and holding the Queen’s lap. The adorable photo was uploaded by a royal fan on Instagram to commemorate Prince Charles’ 71st birthday.

When Prince Charles was still very young, it was revealed that he wasn’t very close to his mother. After all, the monarch left him under the care of his nannies so that she and Prince Philip could embark on their nine-month tour of Australia and New Zealand.

At that time, Prince Charles was just 9 months old. In the book “Charles at Seventy: Thoughts, Hopes, and Dreams,” royal author Robert Jobson revealed that Prince Charles was left under the care of his nanny, Mabel Anderson, during that time.

While speaking with Express, the royal author said that Anderson served as Prince Charles’ rock especially since he was a sensitive little boy.

“Of course, in a different way, Her Majesty the Queen Mother, The Queen and of course his wife. The Duchess of Cornwall is a paramount female figure in his life. But Mabel was a key person in his formative years. She was always there for him and he cared for her deeply,” he said.

Anderson wasn’t trained as a nanny when she first joined the royal family while the Queen was pregnant with Prince Charles. But Her Majesty decided to hire her because of her quiet and unassuming personality.

“It was Mabel who put Charles to bed, told him stories, patched up his cuts and bruises and hit upon the idea of teaching the royal corgis to hide and seek with Princess Anne so that she wouldn't miss Charles when he started school,” Jobson said.
