Princess Diana will forever be remembered in the hearts of many, and not just because of her tragic and unexpected death in 1997.

She devoted much of her life to helping others, including her extensive charity work with organizations like Landmine Survivors Network and Royal School for the Blind. To her, loving people and helping those in need was part of her life’s mission. She even once said:

“Nothing brings me more happiness than trying to help the most vulnerable people in society. It is a goal and an essential part of my life — a kind of destiny. Whoever is in distress can call on me. I will come running wherever they are.”

While helping others in need was always a top priority for Princess Diana, the No. 1 priority in her life was always her two children, Prince William and Prince Harry. And with Meghan Markle’s due date rounding the corner (she’s literally due any day now!), many avid royals fans are wondering how Prince Harry and Meghan will adjust to parenthood.

So in honor of the upcoming arrival of Baby Sussex, we’re taking a look at some of the most iconic vintage pictures of Princess Diana and her children. Check out these throwback photos!
