My FH has 2 younger half siblings. In their weddings FH walked their (the siblings) mom down the aisle. Note that they all share a dad who is not involved. Wondering how to include them in our wedding as both of our moms will be walked by their husband's. I'm cool with them in the wedding party but someone told me it would be weird since he wasn't in there's. I asked why that's weird and they said it would make the siblings uncomfortable?? For his bro the sister was his only bridal party member. For the sister younger bro walked her and gave her away.
