I went to a wedding last month, and there were a few little girls floating around in white. Some of them were bridesmaids (including the B&G's DD), but I'm sure not all of them where.
We got chatting to one couple with a 1YO DD. She was dressed in a white dress with little white shoes. She looked delightful. It didn't occur to me to think that the parents might have an agenda, and were 'so precious' that they couldn't bear for the attention to be on anyone but their DD. Because they seemed like really lovely people, and were good friends of the B&G.
Not one of the actual little bridemaids noticed, let alone cared that there was at least one non-bridesmaid girl dressed in white, because they were having far too much fun with all the other kids there.
I find the idea of girls getting upset because another child has (more than likely inadvertently) upstaged them, quite unpalatable. If it were my daughter, I'd be telling her to take a deep breath and to get over herself quickly, and to go back and enjoy herself. Which she would, if a big deal wasn't made about it.
Pandering to it, on the other hand, and making her think she had an actual grievance is just shock to my mind.
I cannot imagine this thread playing out over on Dadsnet, with the genders reversed, in a million years. And that says a lot about us.
yes to everything you've said
