I absolutely agree, the maternal grandmother was there at the birth of our grandchildren and my son, at the time, complained, she, the grandmother edged him out, by hanging on to his daughter too long and not letting him hold her. We came along to the hospital, at their request, to see our new granddaughter the next day and the omnipresent other grandmother was still there letting everyone know what they could and couldn't do. My husband let it all wash over him, he was already a grandparent and this was his 4th grand daughter so he he told me he largely ignored her directives and put it down to her being over awed, as like me this was her first grandchild
I also find the "professional grandparent" a pain in the arse, those who make it their business to take over the raising of the next generation, like they haven't had enough of it first time around! and then talk of nothing else, this all consuming one dimensional so called status defining their whole existence. I feel sorry for those women who are made to feel that they aren't part of some invisible club if they haven't had grandchildren, or even children for that matter.
We all love our grandchildren, I very much regret not seeing much of mine during the lockdown, but far worse for those whose grand children are overseas.
