You are still causing a child to not be born.
Barring your interference a child would be born. But you make the choice and so now a child is NOT going to be born.
This could be applied to using contraception or abstaining from sex when offered it. It's more direct interference, as the conception has already taken place, but all of the above are causing a potential child to not be born.
