The Prince and Princess of Wales completely overhauled their family unit around the time they became parents to Princess Charlotte.
According to the claims, this was done to shield her from the 'peril' of being the next spare.
For those unfamiliar with the situation, British broadcaster Helena Chard come forward to Fox News Digital and outlined the Windsors' concerns.
She said: "Prince William and Princess Catherine know only too well the perils of the heir-and-spare relationship dynamic."
"We know of numerous heir-and-spare cycles, the spare going slightly off the rails, usually due to feeling undervalued," observed Ms. Chard.
To avert the fates of Prince Andrew and Prince Harry, she stated that "the Prince and Princess of Wales are taking every step, a conscious decision to prevent the heir-and-spare cycle with their children."
"They are well aware of the pitfalls Princess Charlotte and Prince Louis could face growing up with Prince George."
However, "The Prince and Princess of Wales know their minds and are carving out their royal path." They are not hesitant to adjust and amend conventional royal customs and laws since "they prioritize their family."
Overall, "their children come first," the expert added. In return, "the children are given the love, support and guidance needed for a balanced, successful, healthy future."
"They are aware that their parenting decisions are critical to the success of the crown," she noted before concluding.
