Just as Middleton famously held her sister’s train during her royal wedding to Prince William, her big sister returned the favor on her special day. And now they briefly shared a moment in the next big milestone: pregnancy.
Already mom of three children—4-year-old Prince George, 2-year-old Princess Charlotte, and the newest member, a baby boy—Kate has plenty of sage advice (and designer maternity clothes!) to pass on to her younger sister.

A source previously told PEOPLE that Middleton and Matthews are looking forward to settling down and “having children and leading a quiet life.”
Pippa’s pregnancy also comes after her father-in-law David Matthews was reportedly arrested in March following accusations he allegedly raped a minor in the late 1990s, according to the Agence France-Presse (AFP) and The Telegraph.
The charge reportedly relates to an incident that allegedly took place between 1998 and 1999 in France. A complaint was made about the alleged attack in 2017.
