AITA For telling my sister that her new boyfriend can’t bring his child to my wedding?

Wedding plans often come with a host of expectations and boundaries, and when these are crossed, tensions can quickly rise. The issue in this story centers around a woman in her early thirties who is getting married in November 2024—a wedding that has been meticulously planned for two years.

Her sister, freshly divorced and now dating a colleague (referred to as Brandon), assumed that because she was the maid of honor and her new relationship was already in its early stages, Brandon would be allowed to attend as her plus one. The conflict escalated when it emerged that Brandon intended to bring his daughter, Kelly, to the wedding, despite the clear “child free” policy communicated to all guests.

‘AITA For telling my sister that her new boyfriend can’t bring his child to my wedding?’

Family events, particularly weddings, require clear communication and firm boundaries to prevent misunderstandings. According to Dr. Laura Simmons, a family relationship counselor, “Setting and enforcing boundaries in family gatherings is essential, especially when emotions and expectations run high. When a host has clearly stated rules—such as a child free wedding—it is both reasonable and necessary to insist that these guidelines be respected.”

Dr. Simmons adds that while it’s important to be flexible in certain circumstances, overriding a clearly communicated policy can lead to long-term resentment and conflict. In this case, the bride’s decision to not allow Brandon’s daughter is rooted in her personal vision for the event and the desire to maintain consistency with her communicated wishes. By insisting on these boundaries, she is taking a stand to ensure that her special day reflects her priorities and values, even if it means facing temporary familial discord.

Here’s the input from the Reddit crowd:

The Reddit community largely supports the bride’s decision. Many commenters stress that a child free wedding is a non-negotiable stipulation that all guests were informed of well in advance, and that Brandon’s assumption to bring his daughter is out of line. Some advise that the responsibility lies with Brandon and the sister to respect the established rules, while others even suggest having security or designated personnel ready to enforce the policy. Overall, the sentiment is that this is the bride’s day, and if the rules are not followed, the consequences should be clearly communicated and upheld.


Ultimately, the question boils down to personal boundaries and respect for the host’s wishes. The bride stands by her decision to maintain a child free environment, emphasizing that her wedding is a carefully planned event meant to reflect her vision and values. While this stance has created a rift with her sister, it also raises an important discussion:

How should family members balance personal desires with the need to honor the host’s guidelines in major life events?
