No kids under 10

10 is an unreasonable cut-off age, in my opinion, because you're running a greater risk separating families, which is rude. Families are social units; you can't just invite Aunt Mary, Uncle Bob, and Cousin Amanda (age 15) and not Cousin Timmy (age 7).

Most people recommend 18 as the cut-off.

ETA: Also, if the baby is a newborn, it's important not to separate them from the mother. Do not be offended if she declines. It happens.

Reasonable cut-off. I'm having no children.

10 is a random age. What if a family has a 9 year and a 14 year old? You expect them to find a sitter for one kid? Going completely kid free is fine but don't split families.

I would allow newborns.

If the baby is still being breastfed by the time of your wedding, it would be not nice to not allow them to bring the baby.

PP brought up the point about 10 being a weird cutoff age. Just set it to 18, and people will understand.

I want to do the same thing, only problem is my fiancées mom keeps saying how I can't say no younger children because there are people who won't be able to come without their kids. I'm sorry, that's not my problem and it's my wedding.

I'm on side all kids or no kids. 10 is an unreasonable cut off age that could split families.

Well that's an arbitrary number? What if you have a sibling who's 9 and one who's 11? You can't break up families, that's against etiquette. Pick something else like 18, 19, or 21 (depending on area drinking age).

You shouldn't tell a new mother she can't come because she has a newborn.

And you absolutely can't expect her to come without her newborn. How is this a question?

I agree with PPs. My oldest will be 10 by your date and my youngest will be 8. I wouldn't be leaving one and taking the other. Also, they are both equally very active boys. So the oldest doesn't sit more or speak quieter; they're kids. We're having a kid free wedding other than those in our wp.

You can't say no newborns. Even in 18 plus or 21 plus weddings, newborns are the exception. Or expect a decline (and by the way, inviting someone knowing that they will decline is tacky and gift-grabby).

ETA forgot can't use symbols

@Chelsie is your fiancé's mom paying for your wedding? If not, then it's not her say.

Unless your FMIL is paying for the wedding in some way, she really doesn't have a say on you not inviting children.

10 is not a reasonable cut off. Either make it 18 or 21. Your sister's baby should be invited if she is breastfeeding.

@chelsie are you doing no children or no younger children? If it's no children, then she doesn't have a say. If it's no younger children, like the OP is proposing, then she's right to call you out.

You need to make the age 18 or 21 and adults only. Don't throw out a random number as it could possibly split families.

If my math is right the baby would be around 10 months at wedding? Tell them to get a sitter and you are having an adult only wedding.

Why is 10 your cut off? That's such a random number. And like others have said you risk splitting up families. Which is so rude. As far as your FH mother, if she isn't paying she gets no say. If people can't leave their kids, then they don't come. Which is fine. But don't split up families.

Newborn infants and nursing babies should always be allowed to come with their parent.

We did 21 and up, like almost every wedding we've ever been invited to. Our venue didn't offer a discounted bar rate for guests 13- 20, unless they were 12 and under and would accept the kids' meal, which isn't a guarantee with a lot of kids. They also had the right to ask every guest, for a photo ID, every time they visited the bar; if someone under 21 tried to get alcohol, they could have shut the bar down, for the rest of the evening. We were not going to run that risk, nor pay for 5-hours of top-shelf open bar, for those who weren't 21.

I agree with pp- I'd make the cut off higher age or non at all- nursing moms are the exception- can't ask her to be away from the baby- it's not as easy as leave with sitter and some breastmilk
