Blended family ceremony rituals

We are using a blended family vow that incudes all of our children. I got the idea from a sand ceremony site. We are doing the sand part, but you could leave it out and just do the vow piece. Here is what it says:

(To the kids

Each of you is now a resource into which, as family members, you may come to, throughout your life times, for direction, meaning, and love.

Your Parents strive to provide not only the basic needs, but a nurturing and loving environment in which each of you find the confidence to reach the highest goals of your hearts, minds, and spirits.

This is part of their vision of what your family is. Do you each accept the responsibility of being an important part in the building of this family, and to forever contribute your best efforts to maintain the closeness and strength? If so, say, “We do.”
