If you have children from a previous relationship, or have other young family members, you might consider making these kids a part of your wedding ceremony. There are many meaningful ways for a child to be included. But since kids can be unpredictable, you’ll want to make sure they are playing an appropriate part for their age, and that you’ve done everything you can to make them comfortable.
Children might not do everything you think they will during the ceremony – it won’t be perfect but it will probably be cute and entertaining.
Whatever you do, be sure to be patient with children. They may get suddenly shy, or uncomfortable with what’s going on. In the end, let them do as much as they are happy doing.
