This video shows you how to deliver a baby.
There are several steps. The first one is labor and it comes in various time frames. Once dilated to 10 centimeters, the mother will begin to push.
Then, the baby's head crowns, which spreads and stretches the labia apart. After the head crowns, the head will then come out. Put some gentle pressure on the top of the head so the anterior (top) shoulder can be delivered first, then the bottom shoulder.
You then suction the nose and mouth, deliver the rest of the baby. You clamp and cut the cord, and collect some core blood and finally, you deliver the placenta.
That's how you deliver a baby.
