Our first child is due in July and we're trying to figure out what to call my dad's partner. They are not married but have been in a relationship for about 3 years now, so she seems to be a relatively permanent feature.
The thing is, I don't want her to be called the traditional "nana, grandma" etc as I don't want to take this away from our biological mothers.
Just wondering if anyone is/was in the same position and what you called them. Or even if you haven't been in this situation and have some suggestions that would be fab!
