Once your cervix is fully open, you can push your baby out.
You'll feel the pressure of your baby's head between your legs. With each contraction you may get two or three strong urges to push. Listen to your body and push when you get a strong urge. With every push, your baby will move down a little. Try not to hold your breath when you're pushing.
At the end of the contraction, he'll slip back a bit. Don't worry. As long as your baby keeps on moving a little further each time, you're doing fine. When your baby's head is far down, you'll probably feel a hot, stinging sensation. This will happen as the opening of your vagina starts to stretch around your baby's head.
The clinic sister or doctor will tell you when she can see your baby's head. She may ask you to stop pushing and take short, panting breaths for the next two or three contractions. This helps make sure that your baby is born gently and slowly. It helps you avoid tearing.
