To have kicked MIL out over baby’s name?

Frankly, I don’t care if you called your daughter Chrysanthemum Araucaria: she’s your daughter, and you get to call her what you like, and your MIL says, “What a lovely name”, or “What an unusual name” or similar - and that’s it: end of conversation. Your daughter, your choice. She is a fool, because five bob says she wants to see your daughter more than you want to see her. A wise MIL knows her place.

SIL can sod off this has nothing to do with her.
You didn't kick her out, you gave an adult and warning about their behaviour and they didn't listen so she suffered the consequences.
She's the one that ruined the visit, she should have been so enamoured with her new grand baby that even if she didn't like the name she would have kept her mouth shut.
I don't know why other family members feel like they have any right to complain especially once the baby is already here.

Why on earth should you apologise?
Does she have form for ruining special events?
It's a Narc trait

Let her stew, don't discuss further with anyone else and enjoy the peace with your new baby

How long ago did you give birth op?

Ignore SIL, it's not you who have made things difficult.

But there’s ways to say something and ways you don’t.
Thats very unusual , not a name I’d have thought you’d choose vs That’s a horrible name, she’ll hate you for it.
And she should have realised that’s what you’ve both chosen , that’s her name, she can’t change it so she sucks it up whether she likes it or not.
And you’ve got nothing to apologise for — she was out of order.

if The name was just not her taste, then you are not unreasonable.

if we are looking at a case like “Talula Does The Hula From
Hawaii” then she may have just been trying to save your child from torment.

Whisky I wouldn't have behaved as your mother in law did I would absolutely say something if the name was bloody awful!

and… people have started listing names they consider ridiculous, including some I know/have
🍿

How recent is “recently” OP?

You're not being unreasonable and it's so refreshing to read one of these threads that ends with 'and then we kicked her out' as opposed to the usual 'and no one said anything and I wish my DH would stand up for me'. Fair play.

Yep, this. And Princess FluffyBollox has just become the preferred nickname of my supercilious, house ruling cat !!

You didn’t kick her out
Her son did
and he wasn’t being unreasonable but I’m guessing that this behaviour is hardly surprising to either you or her so.

Go on then- what have you called her?

Obviously she was totally in the wrong. You were right to bollock her. Horrible woman, really.

However.. what if the name Is ridiculous/ might mean your child would get teased later on. No one wants a dodgy name. She might be doing you a favour being so brutally honest. Even though it’s a misguided way to do it.

The MN jury would give you an answer yey or nay.

Tell her you’re not excluding her, she excluded herself being tactless and rude. Tell her she’s perfectly welcome to come back when she’s grown up and can muster up a decent apology. And if she can’t do that, and behave better in future visits she will have nobody to blame but herself.

You can't ask us to judge without saying the name!

She sounds like an absolute f-ing nightmare. Is this your first child? This will not get better. If this were me, I’m not sure I’d want her in my child’s life going forward. It’s good your Dh is supporting you. Let him do the enforcement of boundaries so that you don’t get demonised. She sounds like a horrible person though.

Very rude so you were right to throw her out.
But we need to know the name, just in case she was trying to save you from yourselves and has genuine concern
When DC were small one of their friends mums named her baby Puck as she loved a midsummer nights dream.
That did raise a few eyebrows.
He now goes by his middle name...

My mum said DS name was “bloody awful, I’m not calling him that”. Told me the next one was “what? You mean like <famous person from the 1970s> child?” And the third “well thank god you didn’t pick the other one you mentioned, it was dreadful!”

Each time, I said she could learn to cope or she could sod off and not see the baby. That focused her mind remarkably.

My dad just rang me afterwards each Tim to apologise and tell me to ignore her.

OP, I don’t think it was necessary to boot her out, but if it felt needed to you, fair enough.
(unless it was actually Ermintrude or Ethel, in which case she’s right)

By the way OP I agree with what you did in regards to MIL but I think you are bang out of order from keeping the name from all of us 🤣🤣😬

Everyone will be on your side OP. But if the name is something too unconventional or odd even, then maybe it’s understandable that she spoke up. You said it was classic but not too common so it doesn’t sound like anything too crazy, but it would help to know the name. If it’s Lucinda, then she’s being a bitch, if it’s Deidre she may have a very valid point.

You were absolutely right to tell her off, OP.

Me and my husband only recently became grandparents for the first time and we resolved that the baby’s name was not our choice and, more importantly, not our place to comment on. It turned out we love the name, but we would never have said anything negative even if we hadn’t been keen. Having your mother in law laugh in your faces must’ve been very hurtful. I’d tell her she self-excluded herself from her granddaughter’s life with her nastiness.

YANBU.
Your SIL might have a distorted view if she is your MILs daughter.
