There are millions of parents who long to adopt a baby[0]. Having a baby does not necessarily imply raising them.

If the other parent doesn't consent to an adoption it usually can't happen. Then you either have to raise the child directly through your labor (custody) or indirectly through your labor (child support).
There are lots of people raising children against their will with no mechanism to relieve them of that duty, even if they revoke consent to raise the child in any form.
But after spending nine months in woman's body the child becomes the part of her life for twenty next years. Should it rather be "my life - my choice"?
