Prince Harry's childhood and playful behavior are now being questioned by a royal expert who believes early discipline could have made a difference.

The Duke of Sussex, who has been open about his strained ties with the Royal Family, is criticized for his 'unwillingness to take responsibility.'

In a new book, author Ingrid Seward suggests that Harry's role as the spare heir allowed him more freedom than his brother William.

She thinks that being allowed to 'play the fool' may have contributed to his attitude of blaming others for his actions.

"As the spare, Harry had always been allowed greater licence than his elder brother. He'd play the fool and get away with childish pranks," she said.

Seward highlights that Harry's pranks, while amusing to his parents, could have been curbed with firmer parenting.

She argues that the lack of early discipline may be behind Harry's tendency to avoid responsibility.

"Later events suggest, however, that a bit more early discipline might have been helpful," she added.

The author recalls instances where, as a child, Harry acknowledged William as the future King, regardless of his own actions.

Harry told Prince William, "you're going to be King; it doesn't matter what I do."

Meanwhile, Prince Harry is reportedly planning a heartwarming three-day visit to Canada along with Meghan Markle.

The trip, from February 14 to 16 holds special meaning as it brings the Invictus Games back to a previous host country, introducing winter adaptive sports.

Additionally, the royal couple, known for their affectionate connection to Canada, may celebrate Valentine's Day with a vow renewal ceremony, marking the location of their 2017 public debut.
