Regardless of much time Diana spent with her children, it is obvious from her children's perspective, it was quality time well spent so that they have those extremely fond memories now.
A decent historian can have biases too, no matter how many second and third party sources they may have. After years of reading from the perspective of the so called historians, biographers, friends of the ex, friends of the mistress, ex employees of the palaces, disgruntled staff, overnight journalists, former friends etc, I'm looking forward to Diana's children's perspective.
IMO, having a second party describe Diana's love for her children is completely different from the children describing how they felt on the receiving end of that love. My own father can describe how his wife loves her children, as the child, I can tell you how I really feel having a loving mother, no buts about it.
As discussed over the last couple of weeks, it seems again there is a preference for some to not want to hear directly from a real source, that is William and Harry; some prefer to hear from the so-called experts and their secret sources, as if those so-called insiders don't also have an agenda. Thank you William and Harry for being a direct source, even if it makes the 'middle-people' and their followers uncomfortable.
