The Duchess of Cambridge shared a beautiful new photo of her daughter Princess Charlotte smelling a bluebell to accompany her extremely honest interview about parenting.
The snap shows the young royal crouching down in a section of overgrown grass near the Cambridge family's Norfolk home - and it's very special to Kate.
She released the photo, which she took herself, to support the point she made about the importance of children spending time outside.
The Duchess sat down with Giovanna Fletcher to discuss everything from giving birth and posing for the hospital steps photos hours later to her mum guilt when it comes to leaving George, Charlotte and Louis at home while she carries out her royal duties.
One of the things she talks most passionately about is the benefits of young children exploring the outdoors, saying it's something she loves doing with her little trio.
She said: "There are also the environments that you spend time in as well: a happy home, a safe environment.
"As children, we spent a lot of time outside and it’s something I’m really passionate about.
"I think it’s so great for physical and mental wellbeing and laying those foundations. It’s such a great environment to actually spend time in, building those quality relationships without the distractions of ‘I’ve got to cook’ and ‘I’ve got to do this’. And actually, it’s so simple."
She speaks about the photo of Charlotte as an example of this.
She said: "I’ve got this one photo of Charlotte smelling a bluebell, and really for me it’s moments like that mean so much to me as a parent, and I try everyday to put moments like that in even if they’re small or even if I don’t have time... but that in an ideal world is what I would like to do."

Kate has been widely praised for the candid and honest interview on Giovanna's podcast Happy Mum, Happy Baby, which is by far the most open she's ever given.
One of the points many fans have found the most relatable is her views on 'mum guilt'.
When Giovanna asks her directly if she suffers from it, she replied: "Yes absolutely - and anyone who doesn't as a mother is actually lying.
"Yep - all the time. Even this morning, coming to the nursery visit here - George and Charlotte were like 'Mummy how could you possibly not be dropping us off as school this morning?'
"It's a constant challenge - you hear it time after time from mums, even mums who aren't necessarily working and aren't pulled in the directions of having to juggle work life and family life."
She also says she sometimes feels guilty about the parenting decisions she makes.
She said: "[You're] always sort of questioning your own decisions and your own judgements and things like that, and I think that starts from the moment you have a baby."
She goes on to explain how she deals with the guilt, relaying something a "very wise man" told her.
She said: "The more people you have around your children who are safe and loving and caring, the better.
"So yeah - it was a real weight off my shoulders that actually it's not totally my responsibility to do everything, because you know we all have good days, bad days - and you can dilute that with others who aren't on that particular day struggling.
"I think it makes such a difference for your child, keeping them as constant and happy as possible."
