To hate sister calling my daughter her bestie?

[PennyPolo]

I've never been a fan of the term 'best friends' but my sister has started referring to my 11 month old daughter as her 'bestie' and it's really bothering me.

I don't have a great relationship with my sister. I have to have quite strict boundaries with her because she has a lot of narcissistic traits. We never got along in childhood and although better now can only see her in small doses. I'll never leave my daughter alone with her because I don't trust my sister and I worry about her behaviour. She is a bitchy person and doesn't have many friends. She can make new adult 'besties' and lose them within 6-12 months.

Would I be being unreasonable to ask her not to call my daughter her bestie? Or do I just bite my tongue and let it go?

It depends on what the drama from her inevitably playing the victim would do to you.
Are there parents who would get involved?

If its not worth it I would just restrict how often you see her. Don't allow an overly familiar relationship to form.

Just ignore. Any requests will make her more interested in continuing. Hopefully this will stop over time.

This is harmless. It’s from a place of love.

or from a place of care

pick your battles

Ignore, ignore, ignore.

Her saying it doesn’t make it true!

And when they are old enough, dc usually have a very good radar for bull!

Also, she’s probably just doing it to wind you up anyway! And she’s succeeding! Don’t let her get to you op.

just let it go, adults call babies they love all sorts of silly meaningless nicknames

Just keep calling her Auntie, on repeat.
