AITA for refusing to let my sister bring her kids to my wedding after she ignored my boundaries?

I (28F) am getting married soon.

I have been planning this for over a year.

This woman got frustrated after learning that her sister planned to bring her kids to the wedding.

I explained this a few times, and she agreed.

However, a few days ago, she casually mentioned that she’s bringing her two kids anyway because she doesn’t have anyone to watch them.

I was frustrated, and reminded her that I specifically asked her not to bring them.
