Powerful pictures capture the moment a dad delivered his twin baby boys after climbing into the bath to help his partner during her water birth

The photos, taken by Temecula, California-based birth photographer and doula Robin Baker, shows a couple together in a bath welcoming twin boys after the birth progressed so quickly that the birthing team didn't have time to arrive. 

One of the images in the series, showing the second baby arriving en caul, was a winner in the International Association of Professional Birth Photographers' 2016 Image of the Year Competition.
