FI's very close with his cousins, who are all invited to the wedding, sans children. However, one of FI's cousins recently had another baby. The baby will be a couple of weeks shy of 3 months old when the wedding happens.
FI and I are clueless about babies. Is three months still that very young age where the mother won't want to get a sitter? Is three months still young enough that the parents won't even want to leave the house? We want the parents to come, and I don't want the mother to feel pressured into getting a sitter for the baby if she doesn't feel comfortable with that; however, I think if she also brings the older children the rest of the family, who we told "no kids," might raise their eye brows....
I don't want her to just RSVP no because the invite didn't include the children, so I have been debating calling to congratulate her on the baby and mentioning that we are hoping she can make it to the wedding and while we are unfortunately unable to accomodate older children, we completely understand if she wants to bring the newborn.
OR, should I just wait and see if she calls about the baby? If she does, what's the polite way to say yes to the baby, no to the other kids? Is there a polite way to say this?
