Does anyone else find this a bit creepy?

I could never call anyone but my own mother mum,nd both my mils wanted to be called by their surname, should say ex mils now
My own sons and daughters partners call me by my first name
My second mil would not even acknowledge my 2 children to her son as her grand children,only the ones by his first wife

I don't want to be called Mum by anyone but my own children. Hiwever i am known as Nana by grandchildren and stepgrandchildren as it's too confusing for them all to call me different names.

Each to their own!

Sounds like a case of their hopes and expectations not matching up to reality. Some desperation there? Wouldn't call it "creepy", though.. Just rather sad now I've heard the outcome..

It sounds like they were desperate to make a new family unit unfortunately society puts such store still on "normal" families that people often a desperate to fit in and not feel excluded. I was a lone parent when my children were growing up and I know how left out they felt when visiting happy 2 parent households I also found my social life took a nose dive too when I became a single parent!.
Personally I would be reluctant to bring a full on family approach to a new relationship especially if there are children around as they particularly need stability!
My own SIL's all call me by my first name and I would not want to be called mum by them as I am not their mother and they have their own parents!

Nothing creepy about it just wishful thinking for a future that didn't turn out as expected I myself wouldn't do it or have my son and daughters partners call me mum you only have one mum

To each his own. What we personally find 'strange'!! is normal to another.

One of D's ex boyfriends used to call me Mother. I quiet liked it, they were only teens at the time. Her ex husband and new partner both use my first name.
I never knew what to call MiL so it was 'your mum' 'your dad' I was never brave enough to ask her opinion.
Nothing creepy about op as others say just wishful thinking.

It took my daughters partner 5 years to call me by my name, it was always your nan, your mum, we all turned round in shock, it was so funny.

Surely just because it's easier if you both refer to someone by the same name. Saying "your mum", "my mum" or "your gran" or "Natasha's GCs" is just too difficult, life's too short. My mum is "Nana" to my DCs and DGCs and from time to time I call her "Nana" as well. She also has a range of step GCs and GGCs who all call her Nana. We all know what the relationships are really but Nana is easy and she loves it.
Dave's mother sounds lovely, I hope Natasha keeps in contact with her.

Complicated perhaps. Many families are. Creepy? Nah.

I can only assume that you live a very sheltered life if you think that's creepy.

my daughters in laws always call her two children from her first marriage their grandchildren and treat them as if they were.I think its lovely that they love my two eldest grandkids this way and am happy they do

*iiis was 'ideas'. ?

A friend of mine

After 4 months?? Presumptuous of Natasha and of Dave's mum imho. Doesn't 'mum' have any little great GC of her own from Dave's DC, her actual GC? Natasha's DM must have iiis onthis too.
A friend of always referred to a much loved little boy as 'my step grandson'.

My sons in law call me by my first name which I consider normal but I had forgotten that I could never have called my MIL by her name but as she was German I called her Mutter which I don't like.
And never already after 4 months.

Are the GCs disappointed?

Yes, over-optimistic like one of DS's girl-friends who didn't last very long afterwards.

It doesnt seem creepy to me, more a case of wishful thinking. Guess there is sadness now.

Not creepy but definitely 'jumping the gun'. Lack of restraint on their part but no real harm done.

Sounds as if they were perhaps a bit over optimistic, but "creepy"? Why on earth would you think that?
Sad it didn't work out.

They were happy at that time so no, nothing creepy about it, I feel sorry for them thst it didn't work out

I feel a bit sorry for Dave's mum

Up to them ....if it made them all happy what's to worry about
I wouldn't act like that, in fact both my son in law and daughter in law have always called me by my first name but everyone's different Anyway if they ve split up now it won't matter any more

I find that odd but I know people who do it too. I only have one mam and dad. I call my MIL by her Christian name.
