“When I was really sick, I really saw the power of it, the meditation and deep breathing and things like that, that they teach you in hypnobirthing,” she shared. “I’m not the happiest pregnant person because I had terrible morning sickness.”

When asked if she experienced it with all three children, she confirmed: “Unfortunately, yes.”

Kate also acknowledged the toll pregnancy takes not just on the mother but on the entire family. Whether she and William will have a fourth child remains to be seen, but Tom Quinn’s book suggests they may already have an honorary fourth child in their home—William himself.

William’s Royal Routine and Kate’s Influence

In Yes Ma’am: The Secret Life of Royal Servants, Quinn describes how William’s hectic schedule means his clothes are carefully laid out and his daily routine is meticulously planned. He reportedly bathes at the same time each day, and if things don’t go according to plan, he can become frustrated.

Kate, having grown up in a more grounded environment, is said to help him stay level-headed. Quinn even quotes a royal insider as saying:

“She said he sometimes has to be treated as her fourth child.”
