Step grandparents Royal or otherwise

I felt really miffed on Camilla's behalf at her being totally sidelined when it came to talking about the new baby's grandparents. Commentators kept talking about the baby as only having one grandmother. Like C I'm in the position of being a 'substitute grandparent', my dear SSon's mother not being around[ Not dead, just bloody minded] My grandchildren -as I do think of them - have known me from birth as being in that position. I wouldn't dream of offering advice to my D in L as I've never had children of my own, but I love them to bits and do everything I would hope a g'parent would do. Camilla has had her own children and grandchildren I'm sure she'll be another loving adult in the baby's eyes. Please don't let us go harking back to Diana and what a wonderful G'parent she would have been.
