Grandmother often refers to herself as "Mom"

I do know that when she was in her earlier mothering years, she did send her kids to her mother a lot of the time and my husband often speaks of spending all weekend at his grans house and how he didn't enjoy it. As it was almost an every weekend story. So maybe she's missed out on being "mommy" to small children and now is trying to make up for it? I'm not sure what the reason ishe behind it but it's creepy.

why are so many mums on gransnet - is mumsnet not enough?

Look there's definitely a strained relationship but despite the past, I am and will always to include them in the kids lives, however, when we do see them, I have noticed she refers to herself as above and often. So I wonder if it's to annoy me or because she secretly wishes she was their mother lol...

Tell her to stop it now. No excuses. Doesshe want to confuse the child or annoy you?

My mom is known as Nana by my children and I've never heard my mom refer to herself to my children as "mom/mommy"...so I wondered if it was a normal thing for someone to do on a regular basis...

Thanks. I will correct it the next time I hear it.

Or perhaps on a nicer tone ask her to choose a lovely pet name that is special to her & her GC

You are not being unreasonable, nip it in the bud , or a gentle tease about loosing ones marbles & getting confused!

Can't quite get my head around this. My name tag is indelibly etched in the family circle and proudly so. Methinks I would be quickly queried (even corrected?) by the GC who are 4 and 2 respectively. Yes, I think it would undoubtedly have rankled with me had it happened but I'm sure I would have addressed it on the very first occasion.

She needs gentle reminding that YOU are "Mom/mum" and she is Granny/Grandma orvwhatever.
Easily done, many of us find that Mum/Granny etc slips out. Not a big deal though
