Nieces and nephews at reception?

If you are having a kid-free reception that should go across to all guests, except flower girl/ring bearer.

I disagree with PP. I am having a kid-free reception EXCEPT for my nieces and nephews (ages: 16, 14, 11, 11, 8 & 5) - they're a little bit older than your nieces/nephews ... but 1) I couldn't imagine them not being there and 2) it's not my responsibility to make sure they don't hear profanity, etc in songs or see drunk people. If their parents think my wedding reception will be inappropriate for them to attend they can choose to leave them at home.

Your band won't play anything with explicit lyrics. I'm a singer in a wedding band and we would never do that, as it's unprofessional. I've never heard any other band sing explicit lyrics at a wedding either. So that's a moot point.

You are certainly able to have a kid-free wedding if that's what you want. We only had the 3 kids in the wedding party, who are family, at our wedding. People in my region don't even want to bring kids to weddings, so it wasn't an issue for us. But just be prepared, and accept the fact that your brothers might decline the invitation because either a. they'll be offended that you don't want their kids there, or b. they aren't able or willing to arrange childcare for a whole weekend to come.

You can also invite in circles. It's totally ok to only invite kids of immediate family members, i.e. your nieces and nephews, and not invite the kids of your friends or parents' friends, or distant 2nd cousins. Like I said, we only had wedding party kids at ours, and they are family.

However, it's extremely rude to invite people to the ceremony and not the reception, even a small child. So it has to be all or nothing.

We are allowing the kids in the bridal party and anyone with infants they can bring them. I also don't think its wrong to pick your nieces and nephews. My problem is when it becomes 5-10 kids over 2 kids you know. You have to cut it down at some point.

You can have a child free wedding, and take the chance that some parents will decline.

You can also invite children in circles, with no breach of etiquette, the same as you invite adults.

It is never an "all or nothing" situation when it comes to inviting children or adults.

You cannot forbid the two month old from coming even at a kidfree wedding, without looking bad. Most parents won't leave a child that young for the night, even if they're not breastfeeding where it absolutely is a dealbreaker.

Do what you want about the other kids but I don't think that two children is really a big deal.

When it comes to only inviting to the ceremony and not the reception, yes, it is all or nothing. You can't do that.
