Mil

My MIL will be nana but my mum will be grandma. It’s think it’s just preference? Especially if her other grandchildren call her Nana

I think it makes sense for all the kids to call their grandmother by the same name tbh. My MIL already goes by grandma so we went with that, and my mum is Nana because that's what she wanted to be when we spoke about it. I don't think it's unreasonable to want a say in what your grandchildren refer to you as, unless you're trying to get them to call you mummy lol

My MIL is the same about being called grandma. I think it can be associated with referring to someone as 'old' such as 'I feel like an arl grandma' or 'an arl granny'. We call her nana and my mum gets called nanny. Unless the term grandma holds some importance to you then it may be best just to call her nana, especially if the other grandkids call her nana already.

My mil and fil are Nana and Grandpa and my mum and dad are grandma and grandad. It does make it easier to distinguish between them. I did ask them what they wanted as it’s what they’ll be called for years.

Most mum dont want to called grandma, grannie etc. My mum is nanny in Lithuanion and mil asked to be called nanny. Also i feel like its easier for the little ones to say instead of grandma

It's just a preference and pretty normal/common. Don't read anything into it.

My mum and MIL are both Nanny, my husbands Nan is Nanna 😅 no one wanted to be Grandma 🤣

Nope everyone has preferences and I think it’s normal. My mum is called granny but that’s because my nieces called her that so my son naturally adopted that name for her. His dad mum is grandma and my grandma is G-ma she wasn’t having a bar of great grandma 😂

Think this is quite common. My mil was nannie abd already had two grandchildren and my mum chose Nana.
