How a baby is born?

Answer 1

After about 36 to 38 weeks of pregnancy, a baby is well-developed enough to survive outside the womb. In the process called "labor" the uterus contracts, pushing the fetus down the birth canal. In a period of from minutes to hours, the baby emerges and takes its first breath of air.

Answer 2

The answer is long, long, long. I will try to answer it in a nutshell: it involves the actions of hormones that act on the uterus to make it contract and expel the baby, and act on the mouth of the uterus to make it open. These contractions are involuntary, but are aided by voluntary contractions of the abdominal and pelvic muscles of the mother. The baby also contributes by turning, rotating and positioning self in such a way that it goes out. Or, you can just have a C-section!
