That's incredibly rude when people insist on bringing there children to a 'no-children' event. I have a two year old, I would never bring him to a party when I was told the party wasn't for kids. I'd either get someone to watch him or stay home.
You have to pick your battles, what will ruin your baby shower more? Having to tell your family not to bring your neices, or having to deal with your husband's family? Me personally, I'd rather deal with my family over my husband's. Esp, if mine was the ones being rude.
I wish you the best! I hope you have a great baby shower! :)
I think you should definitely tell your family that you are only accepting those you invited. Children and baby showers do not mix. I think it's incredibly disrespectful of your family to go against your wishes and I would understand your husband's family being upset about it.
I would be calling any family member or friend that is trying to bring a child and tell them that this is a day for you to enjoy and it is not a child setting. Tell them that what ever food or what not has been paid for and the headcount was already in. If you are having it at a hall or something I would tell them that every single person had to be accounted for and paid for already. There are places that do that. I'm sorry that people are making this stressful on you. It makes things like this less enjoyable. Good luck to you
Honestly, I would stick to your guns about no children. 16 year old is okay. But any children at all is gonna start crap. Obviously its your day, you get what you want, and screw everyone else but if you are really wanting to avoid drama, stick to your no children allowed rule. No children or all children or someone is gonna try to start crap.
The children at my baby shower drove me NUTS! They ran around like little heathens and I kept yelling at them, so I don't blame you. I would explain that you informed people that you didn't want anyone under 16 but this particular person is still bringing theirs and you don't want his family left out. Maybe explain it was never your intention to leave anyone out or cause any drama.
