My fiance has a groomsman whose wife is pregnant and due 5 days after our wedding. We are both very close with the couple, so they came to us when they found out they were pregnant, worried about what would happen if she were to go into labor on our wedding day, since obviously her husband would need to be with her. My first instinct was we'll just play it by ear, but they suggested that maybe he shouldn't be in the wedding, just in case. They just don't want to leave us high and dry if she were to have the baby a couple days early. What should we do? We have 7 months until the wedding, so there is still time for my fiance to ask someone else. Thoughts? What would you do in our shoes?
