A unmedicated mum gave birth in just 40 seconds when her baby "shot out" - because of a medical rarity.
Cianna Gonzalez, 24, experienced the Ferguson reflex, when the body 'expels' a child.
Also known as the fetal ejection reflex, it is often seen in home births - but rarely in a medical setting.
Stay-at-home mum Cianna, from Philadelphia, says she felt her son "descending" without control.
And he just slipped out after a three-hour labour - where he was caught by a midwife.
