Keeping the memory of a grandparent alive is extremely important for many families. And the royal family is no exception. In a new documentary about Princess Diana, called Diana, Our Mother: Her Life and Legacy, Prince William talks about how he does exactly that. The movie debuts on ITV and HBO on Monday.

Prince George, who is four years old, and Princess Charlotte, who is two, may never have gotten to meet their grandma. But their dad talks about her all the time.

Prince William also talks about how his mother’s hands-on parenting style greatly influenced his own. Meaning he also wants to be a huge part of his young children’s lives. Aww.

Finally, Prince William jokingly admits she might have complicated how he raises George and Charlotte. While Princess Diana would have loved her grandkids more than anything, she would have been a handful for the parents!

Sounds like fun! We love that Prince George and Princess Charlotte will grow up with loving stories of their Granny Diana.

We can’t wait to watch the full documentary and learn more about Princess Diana.
