Ok so my Mum remarried a couple of years ago and since my DH and I announced our pregnancy, my Mum has already started referring to her husband being called Grampy when the baby arrives which to us, is like nails on a chalkboard! DH and I have never been close to him, just the usual small talk as we don't really get on that well with him (previous issues with treatment of Mum which I don't want to bring up here). I know most people wouldn't have an issue with this however we still (thankfully) have our parents alive and kicking so to us, they will be called their grandparents. My brother already has kids of his own with his partner and they didn't mind as much as to what Mum's husband is referred to so am I supposed to follow suit on this or can I say that we would rather they're referred to by their forename? We really don't want to upset anyone but it really bothers us and I don't want Mum or others to get used to the idea of him being called Grampy! Has anyone else had this issue?
