Weddings can be incredibly stressful to plan, particularly when you're navigating the drastically different personalities and extended family.
Sometimes, the most efficient way to avoid a scene at the wedding, is to lay down the law ahead of time, and warn family members they won't be invited if they don't respect basic boundaries.
WIBTA for threatening to disinvite my parents from my wedding for their behaviour regarding my autistic soon-to-be niece?
I'm getting married next year and we want my fiancé's 6-year-old niece to be our flower girl. She is autistic and when she's excited or there's a lot going on she often fidgets, chews on things, flaps her hands, picks at things, and jumps. She also occasionally makes humming and popping noises. She doesn't have huge problems with social situations, and her parents and therapist are confident she won't get overwhelmed. She's extremely excited for the wedding and for being a flower girl. Every time we see her she talks about it.
