This reminds me of when my niece remarried. She has 2 sons, one daughter... he has two daughters, one son. They did up these little letters for each child. Explaining they are not replacing and never expect to replace their mom/dad so they will never expect to be called mom/dad. But they joined in marriage to add more love in their life and a special love only a husband and wife have. Each child was presented with a ring also. The adults also said vows to the children. It was beautiful. Not a dry eye.. difference being...these children have both parents in their life.
