AITA For bringing my daughter to a childfree wedding?

I, 32F, have a 15yo daughter. My sister, 35F, got married last week. I was her MOH. My sister said that no children would be allowed at her wedding as they are loud and noisy. I brought my 15yo daughter because her aunt was getting married and she wanted to wish her well!

At the wedding, my parents were shooting me daggers, and my sister came over furious. She asked "Who was I to completely disregard her rules?". I was confused until she pointed out that my daughter should not be there. I argued, saying that the reason she didn't want children there was because they would misbehave. My daughter was silent, never on her phone, and was extremely respectful.

I left the wedding early and my parents are blowing up my phone with angry texts. My husband agrees with me, but says I could have handled the situation better. My sister is refusing to speak with me until I apologize, but I don't think I did anything wrong. So, AITA?

Edit: Based on the responses, I understand that I was rude for not at least checking in first. I should have verified whether or not my daughter could come. There was no mal intent, but all the same I will apologize to my sister and daughter. My sister and daughter are very close, another reason why I thought she would have been invited.

Edit 2: I have seen these questions a lot so :The invite was a pretty generic card that said "We hope to see you at our wedding!", with the RSVP info, dresscode, etc. I RSVP'd two people, my daughter and I. I believe my sister thought the two RSVPs were my husband and I. My husband did not attend as he was suddenly called out of town for a work conference. There was a place setting, chair, etc, for my daughter because I RSVP'd two people. I assumed my daughter would be allowed because my sister stated that she didn't want children at the wedding due to noise, tantrums, misbehavior, etc.

Last Edit: I apologized to my sister and daughter, we are all doing well relationship-wise. Thank you for your insight!
