I'm finally under a year until the wedding (yay)! FI has a niece who will be about 3.5 years old when we get married. When we first got engaged FI made a passing comment about how cute she'd look as a FG and I agreed. However, I've been thinking that having her as a FG may not be the best idea. She is a very very shy child, and it probably doesn't help that she doesn't have interaction with strangers or large groups of people (her grandparents watch her everyday during the week and her parents don't have her in any playgroups or anything). I'd say about twice a month FI's parents invite everyone over for dinner......everyone being me and FI, FI's sister and her husband, and FI's other sister, husband and niece. S, 6 people outside of niece's parents, and 4 of us that she doesn't see everyday. Each and everytime (the latest being yesterday) niece and her parents get there and she sees all of us sitting aruond the table she either screams for grandma/grandpa and runs or entangles herself between one of her parents legs and will not enter the room. It usually takes 10-15 minutes of coaxing to get her to come to where everyone else is. My concern is not that she'll have a meltdown on the weddding day and "ruin things", but rather that a. walking into an area/down the aisle where 200 people are watching will not be a pleasant experience for her and b. she would end up screaming/crying for one of her grandparents/parents and someone in FI's immediate family will end up missing the ceremony.
I understand the wedding is still a ways off and she will be a whole year older, but because of when she turns 3, she still will not have been in any sort of pre-school because our area only takes fall admissions so she will not have gained any exposure to large groups of people. My question is would it be wrong to just be completely passive about the issue and not mention having her as a FG and only voice my concerns for the child's potential uncomfortableness if the topic comes up from someone else like FMIL or FSIL? FI has been pretty hands off for wedding planning and my guess is that he thinks I'll just ask his sister about having niece as FG, but since I don't think it's a good idea, I won't be asking FSIL about it. Is that way too passive aggressive? If FI brings it up and really wants her in the wedding I'm not going to object, I just don't want to pro-actively involve her because I really think she'll hate it.
