My aunt wants to be invited to my slumber parties and sleepovers with my friends.?

Why do you want her if she will not let her daughter come?

Whichever one of your parents is her sibling will have to sit her down and tell her it's inappropriate for an adult to attend a kids' slumber party. That's just weird.

Your aunt is being ridiculous. Apparently she does not believe these slumber parties are appropriately chaperoned? Or she's regressing to being a teenager and I can't figure out a decent excuse for that. Don't tell her it's okay anymore. It's not okay. If one of your friends isn't allowed to come unless her Mommy is there too? That's your friend's problem. Don't allow it to be yours too. Your Aunt needs to go play with people her own age. Who does chaperone your sleep overs? Put this on their

to do list and off of yours.

Tell her majority rule, the slumber party is only for your friends.

Is this the aunt with mental health issues, the aunt you've posted about over and over and over? The aunt who hates you?

You cannot control anyone else's behavior.  If you are talking "sleepovers" there are parents involved.She's somebody's sister.  Have that parent talk to her.

I don't know what's creeper - her behavior or this question.

Aunts do not belong at sleepovers. She's creepy

Your Aunt needs to find friends her age.

Forget her. Can I come?
