I disagree that having eight children in ten years is completely different than having six children at once. Both situations involve having a lot of little children who need care.
But if you prefer those credentials, I worked in day care centers in which I was the sole caregiver for six infants, all of whom were the same age. I cared for those babies for about the same number of waking hours that Kate did... only I had far less help than Kate did and does.
Really... I'm tellin' ya... raising or caring for a large number of little children doesn't have to make one a stressed out joy killer.
You moms of one or two cuties need to give yourselves more credit. I'm right there with you in having felt frustrated and controlling with "only" two children under foot. But you would probably do a fantastic job if six more sweeties were dropped off at your door!
I have seen enough show footage, interview footage and read enough behind the scenes interviews to be very comfortable armchair diagnosing Kate as being a narcissist.
