No place in that law did I see the word fetus. Now you claim to know what they are trying to explain but they are not using those words.<quoted text>
That is for the purpose of defining what the language in the legislation means to the legislators. They are letting you know that when the write "unborn child" that they mean "fetus." They could have written the same law calling fetuses "fetuses."
They could also define a cocker spaniel as a child in another piece of legislation, and then you would know that wherever the law referred to a "child," that cocker spaniels were included.
Remember, the Thirteenth Amendment called black people 3/5ths of a person for a specific legal purpose. It didn't make it true biologically.
And the law you cited doesn't make a fetus a child, born or unborn. Children are terrestrial animals that breath air. A fetus is a marine organism. Children don't survive without air, which is why they do so poorly in abandoned refrigerators.
It is very specific. It refers to a Child in Utero and explains exactly what that means and it does not say fetus.
