My FI and I are having our wedding and reception at a historic mansion with antiques that will go from 5:30pm-9:30pm. Our friends and family with children tend to have "extreme" ages (infant/toddler or high school). Our reasoning for not inviting the children under 10, include the "late" start, the antiques, and that when young children get "fussy" it can interrupt/ruin everyone's time (the parent who needs to tend to the child, the people in the row that need to shift/stand, and of course the ceremony). What would be the most polite way to word the save the dates so our friends and family understand that children under 10 will not be invited?
