Speculations are rife that Kate Middleton could be pregnant with her fourth child. If a recent statement made by a parenting expert is anything to go by, however, it looks like the Duchess of Cambridge is not going to have another baby anymore.

Kate has been doing a great job as a mom. Many consider her and Prince William as ideal parents, especially when they share photos of their special moments with their three royal children, Prince George, Princess Charlotte and Prince Louis, on their Instagram.

Now that Prince Louis is already one year old, many royal fans speculate that Prince William and Kate are already preparing for their fourth child. In fact, rumors have been swirling around that Kate may already be pregnant with baby number four. According to a parenting expert, however, there is a huge chance that Prince Louis would be their last, and the royal couple knows it.

The expert revealed that Kate’s body language whenever she is with Prince Louis suggests that the Duchess of Cambridge is so fond of her baby and wants to baby him for as long as possible because she knows she will no longer have another baby in the future. Her behavior toward her youngest child shows that she has a special bond with Prince Louis, and this may be because she believes that he will be their last baby.

“As a mum of three, I completely understand how it looks as if Prince Louis is Kate Middleton’s favorite child,” said parenting expert Victoria Jennings. “As a parent, things go by in a flash and so you want to nurture the youngest child for as long as possible, this was certainly the case with me and my youngest daughter,” she added.

Jennings said that Kate is often seen doting so much over Prince Louis because she wants to enjoy his baby years while they last. Her closeness to Prince Louis could be a sign that she knows she won’t have any more children, so she wants to make the most of his early years. The parenting expert also revealed that having three children is already much of a juggling act for Kate as she needs to juggle motherhood with all her royal duties.
