My wedding is 6 weeks away and we are getting rsvps back now. I got one from a friend who has a 7 month old baby. On the reply card she wrote "mr and mrs so and so and baby Jordan will be attending". On the invite the envelop was addressed to mr and mrs so and so. We did not specifically say children were not invited as it is implied on the invitation that it's a formal wedding.
I have no problem with them bringing the baby however my in laws are paying for the wedding and my mother in law has made it clear that she does not want children there. I had to fight with her to invite her own cousins kid's family who's daughters are 10 and 14 (they live out of the country and we are hoping by including the kids they will come).
I have no idea how to approach this subject with either my mother in law or friends. I have invited a few other people and they have children but they know not to bring them (or want a night out). Our son will be 18 months and of course he will
