DH's aunt keeps posting on my FB and DH's FB that she wants our baby to come early since she's in town this weekend. We told MIL about it and realized she hadn't informed her side of the family we're holding off on visitors for a couple of weeks.

This is kind of a big deal, because (I wrote a thread on this a while back) they are having a huge family reunion 6 days after my due date and 30-40 family members will be passing through town and they all want to see the baby. MIL told them it was fine and gave them our address! We told her it was a no-go and that she needed to let them all know that we won't be allowing visitors at that time (if LO has even arrived yet). She still hasn't said anything to them about it. They're all still going on about meeting the baby on their way to the reunion!

DH and I don't have phone numbers or email addresses for all of them, but they're all on Facebook and they have a private group specifically for their family. Would it be appropriate for DH to post something there or should we remind MIL (again) to handle it? Its her siblings and their spouses and children. He would say something like "We are so happy you're excited to meet baby, but per our pediatrician's recommendation and for the sake of settling in, we won't be having visitors until ____ date. We can't wait for you to meet him at the next get-together."

I am probably the first woman in the history of ever to wish to be overdue. That would make this a non-issue
