Activity for Elizabeth

Hi everyone! I’m looking at my options for place cards...does anyone know the rule about place cards for children? A couple of people in the bridal party have children and they’ll have to sit at the head table, do they need a place card as well?

Does anyone have any recommendations on where to get bridal party PJ sets? I'd like them to either have a monogram on initial. Hoping to get a good deal on black Friday! Thanks!
