We are having a childfree wedding later this year. This has not been a big issue so far because it's a small, lowkey, non traditional city wedding. There are no bridesmaids or best men and only a handful of the guests would have small children anyway.
However. One guest has made it very clear that her 8 year old DD REALLY wants to be a flowergirl. Whike that's not at all what we had in mind, for reasons specific to the situation I am inclined to say okay. The dd can put on a pretty dress and throw petals around if she'd like to. But the issue is she will be the only child there, and the only person she'd really know is her mother.
In this scenario, would you expect that child to be there all day? Would it be unreasonable to think she could come to the ceremony, stay for a bit of the reception and then be collected? I will discuss it with the mother but I want to be prepared for her possible reaction. TBH I am already surprised she asked for her child to be a flowergirl, so not really sure what else she might think is normal!
