DB is marrying a Canadian woman in Canada next year (they live there). She wants my children (toddler twin DSs and pre-school DD) to walk down the aisle with her and me and DSis to escort them down the aisle. She’s asked us to wear long navy dresses to fit in with the bridal party and to get ready with them in a hotel adjacent to the venue. However, she has excluded us (me, DH, kids, DSis) from the rehearsal dinner (because it’s for the bridal party) and we’re not on the order of service. She says this is because if the kids aren’t in the mood to walk nicely then there’s no obligation. Fine. But my sis (and me a bit) are really hurt at not being in the wedding party but yet being told what to wear and when and where to get ready.
