Kate and Pippa Middleton share a close bond with each other as siblings, and the Duchess of Cambridge has also been helping her sister throughout her first pregnancy.

Latifa Yedroudj, a journalist for Express, said that the Middleton sisters were also pregnant at one point because Kate didn’t give birth to Prince Louis yet when Pippa announced that she and James Matthews were expecting.

“Because of their close bond, Kate is expected to help Pippa adjust to motherhood and offer all sorts of baby tips on clothing, food, and what it is like to be a first-time mom,” the journalist wrote.

Yedroudj also noted the fact that Pippa helped her older sister during her pregnancy with Prince George. At that time, she even shopped for clothes for the future king with the help of their mom Carole Middleton.

In related news, Pippa is expected to give birth later this year. After surviving her first trimester, the tennis enthusiast penned a column for Waitrose and shared details about her pregnancy.

“When I learned the happy news that I was pregnant, I realized I needed to adjust my 4 to a 5-day-a-week routine. I’ve been a tennis fan since childhood, as player and spectator, and have been keen to continue playing safely throughout pregnancy. Take Serena Williams – she famously proved that women can play a high level of tennis from two months (when she won the 2017 Australian Open) up to eight months,” she wrote.

In the same column, Pippa also said that she didn’t suffer from morning sickness like Kate. Prince Willliam’s life struggled with Hyperemesis Gravidarum (HG) during all three pregnancies, as confirmed by Kensington Palace.

“I was lucky to pass the 12-week scan without suffering from morning sickness. That meant I was able to carry on as normal,” she said (via People).
