My precious daughter exists because the wonderful family who created her wanted to give those embryos a chance at life, and we wanted to, as well. An excellent way to build a family.
Your daughter is a beautiful blessing!
It's a shame that more families that go through the IVF process do not offer their unused embryos for adoption as in your case. You are correct, this is great way to start a family, and you have literally saved your daughter from death.
It is sad to realize that the overwhelming majority of unused embryos do not have the loving outcome that you and the genetic parents have provided.
May God continue to bless your beautiful daughter and her parents.
