I got an email from my cousin asking if kids were allowed at the wedding (they're not). She also asked if there was anyone I knew well enough to trust to watch her child during the wedding. If not, she said that her husband could stay home with the baby. I got the impression she was just looking for me to set her up with a babysitter, and I could probably do that, I'm just wondering how to word my response. FI really doesn't want to pay for a sitter. Should I say "sure my friend M from high school could do it and she charges x." To be honest, M would probably do it for $50, and I kind of wouldn't mind paying the money so that other guests wouldn't have the same issue. I feel like $50 is a lot for one guest to pay, but if I paid it, I think other guests might bring their kids and not have to worry about finding sitters, since the guests are mostly family and the whole family will be at the wedding. What do you ladies think is the appropriate response/action?
