Does Jehovah view the life of a child as precious even during the very early stages of development after conception?

The Scriptures show that Jehovah takes notice of the life of a child even during the very early stages of development after conception:

Ps. 139:13-16: "You [Jehovah] kept me screened off in the belly of my mother. . . . Your eyes saw even the embryo of me, and in your book all its parts were down in writing."
