My FI's brother and sister are part of our wedding party. But, I would like to include their spouses (FSIL and FBIL) in some way. We're having a Catholic mass, so I would like to ask them to bring up the gifts. The snag is that they will both have infants at the time of the wedding. I assume their parents (grandparents of the babies) can watch them while FSIL and FBIL bring up the gifts. Would it be ok to ask them and let them decide if they're comfortable leaving both babies alone (with the g-parents) while they bring up the gifts? I want to include them but I don't want them to feel obligated to do it, espeically if they're concerned about leaving their babies while they do it.TIA!
