Ashcombe
When I married DH olddudders, I already had children, grandchildren and step grandchildren with the latter calling me Grandma, as their step siblings do. As DH has no children, he wasn’t a grandfather so was fine being called by his first name by all his new family. At the time, he said to the grandchildren that, with both grandfathers being alive, he was happy for them to use his first name.
My ex's new wife has insisted on being called Nanny …………. (first name) which was her choice but only her own children call her Mum.
Overall, I feel the quality of the relationships between the generations is more important than the names used. Mutual respect has grown between my DH and his newly acquired family members, which is a joy to me because it could have been very different.
Exactly so. My short forename is easy for the very young to catch hold of, and I am more than happy to be addressed as such, as I would be by adults. Ashcombe's natural daughter - she also has an adopted one, who isn't quite as natural, perhaps! - and I were at loggerheads for a while before Ashcombe and I became an official item. Her willingness to accept mum's decision, once it became clear I was genuine (I had been widowed) means I would do anything for her or her children.
I recognise the OP's dilemma, but family peace is a prize worth treasuring if hubby can swallow his pride.
