A child 5 seconds out of the womb is no different than a child 5 seconds before birth.
Technically, the former has lungs filled with air and the latter has lungs filled with fluid. Is that a significant difference? Probably not, which is why abortions are banned post-viability.
There's no fairy waiting with a wand at the birthing table to magically bestow rights on the child once he or she comes out.
Potentially there is the Holy Spirit entering the newborn baby when it takes the breathe of life, which I find amusing, because it makes the best unrestricted abortion argument a religious one.
