I'm nowhere near the grandparent stage, my kids are 19 and 21 (and no guarantee they will want their own!) but I've been thinking about it a lot lately for some reason, trying to imagine what it would be like. I can't imagine loving someone as much as I do my kids, but I do remember worrying when I was pregnant with dc2 that I wouldn't be able to love them as much as dc1, and that was obviously bollocks.
So just curious really, plus I am stuck on the sofa with Covid and a torn shoulder, so nothing to do but overthink things!
