I think ideally abortion is not allowed with exceptions being rape, underaged, below the poverty line, or a confirmed stillborn/mother will die. Well I should specifically say that these should be excepted.
But at least there should be a time limit, I hear some states allow up until birth which is definitely straight up murder. According to this growth chart https://www.cdc.gov/dotw/fasd/images/chart_928px.jpg the brain starts developing at week three.
There have been studies on if the fetus will react to outside stimuli, such as music, so perhaps you shouldn't be allowed to abort if it's already able to react to such stimuli (with exceptions of course)
For some reason the right generally prefers foster care and foster care is almost always just plain bad and I have no ideas on how to fix it.
As for adoption the right also likes to put rules on adoption, I think anyone over the poverty line and over 18 should be allowed to adopt (I think some examples of said restrictions were no gay couples and no transgender couples)
