AITA for kicking out a kid out of my wedding reception after she ruined my costume

Hey Thunder crew I'm a new listener but decided to post my story here to seek advice from you all.

English isn't my native language so apologies in advance if somethings don't make sense

I (27M) and my husband (33M) got married a little over a month ago we had a small destination wedding and reception in a hotel me and my husband love.

With small i meant around 10 to 15 people all family and partners and kids. De reception was held at a small conference room the hotel has with a bar etc now to the problem.

My brother in law (36M) has a girlfriend (35F) they have a kid together a 3 year old boy and the girlfriend has a daughter from a previous relationship a 9 year old girl now she has something we call "a princess complex" better known as main character syndrome and will do anything in her power to have the attention on her if it isn't.

She was misbehaving the entire time like interrupting speeches, screaming at the top of her longs for no reason, demanding that the dj change the music and that everyone needs to leave the Dancefloor so she can dance on her own. She also knocked over several glasses "on accident".

I talked to my brother in law and asked if they could keep her in check because she is ruining my wedding he just shrugged and said "not my kid dude talk to her mother" i sighed but said "okay" and talked to the mother and she literally said "she's just a kid thats what they do" i said "no my nephews are here too and yes they do stuff but when i tell them to take it down a notch they say sorry and behave" my nephews are 2 boys 1 is 9 and the other is 13. Her response to that is that i am too bossy and she doesn't want her kid to be pushed around like that.

Now i saw this coming unfortunately so i rented out the kids club of the hotel plus a cast member to supervise if needed. Everyone knew this and I also put it on the invitations because i know keeping kids still and behave is difficult plus they will get bored eventually so they could go there and have fun without a worry.

Now the straw that broke the camels back was when dinner was getting served and she "accidentally" knocked and broke my wine glass spilling red wine over my costume she wanted to show something to het mother on her Ipad or whatever and looked at my smirked and said "sorry" in her typical mocking way.

I had it i stood up signed the staff to come over and remove the child from the conference room to the kids club. While escorting the kid out the mother stood in front of the door and demanded that they let her go and called me over she said that i have no right kicking out her child. I said i do i payed for this event everyone here eats for free got a free room and transport from and too my home country.

I said your kid misbehaved allot and if you're not stopping it she will meet the consequences. She yelled and said that i didn't give her warning which i did 4 times and that she won't let her child be removed. I sighed and said fine if you want to be with her do bad you can accompany her and said that the mother is getting kicked out too.

My husband and his parents said I handled it well and so do my sisters. After the reception she stormed towards me and yelled that its disrespectful to kick out guests at your wedding specially children. Now here is where i might be the ASH i said that if my sister didn't have kids it would have been a child free wedding because i knew your daughter would be a problem.

She scoffed and stormed off and now I'm wondering if i could've handled it differently.

So AITA for kicking out a child of my wedding reception after she ruined my wedding costume ?
