Mothers - "Natural birth" vs Chest bursted hosts

Would I be correct in thinking that how we've seen it play out, be it xeno or shaw. Their "naturally born" babies have always been a variety of facehugger? As we see wth the Alien queen, and Shaw Then then anything that is hugged, or becomes a host always gives birth to a xeno-burster? As we saw with Kane in ALIEN, or the engineer in Prometheus
