Grandparents can be an integral part of a child’s development. They say it takes a village to raise a family and the parents who have the support of their child’s grandparents usually welcome the extra help.

It has been a staggering 20 years since the tragic death of Princess Diana and the loss of such an incredible human being is still felt the whole world over. But on a more personal level now that her children are having children of their own, it’s so deeply sad that they won’t ever get to meet their beautiful Grandmother.

In the new documentary titled, Diana, Our Mother: Her Life and Legacy - Prince William chats about how he tries to make "Granny Diana" a part of his children’s lives. He reveals that he talks to Prince George, 4, and Princess Charlotte, 2, about the grandmother they never had a chance to meet, keeping her memory alive.

"We've got more photos up round the house now of her and we talk about her a bit and stuff."

They get to talking about Granny Diana usually around bedtime, and it usually is up to Prince William to keep it going.

"It's hard because obviously Catherine didn't know her, so she cannot really provide that - that level of detail. So, I do [when] regularly putting George or Charlotte to bed, talk about her and just try and remind them that there are two grandmothers, there were two grandmothers in their lives, and so it's important that they know who she was and that she existed."

In the interview Prince William mentions that he feels that “Granny Diana” would have been an absolute nightmare as a grandmother because she would have taken her role very seriously.

"She'd be a nightmare grandmother, absolute nightmare. She'd love the children to bits, but she'd be an absolute nightmare. She'd come and go and she'd come in probably at bath time, cause an amazing amount of scene, bubbles everywhere, bathwater all over the place and - and then leave."

The impact of the prince’s mother is long lasting with her parenting skills being ones that he would like to emulate within his own family.

"I want to make as much time and effort with Charlotte and George as I can because I realize that these early years particularly are crucial for children, and having seen, you know, what she did for us."
