Kids ASK! about Family & Parenting

In medical terms, pregnancy lasts for 38 to 42 weeks from a woman’s last menstruation date. In other words, it takes 38 – 42 weeks for the baby to be fully developed in his/her mother’s womb.

Doctors usually calculate the expected date of birth by adding 280 to the date of the first day of the last menstruation.

Usually, at the end of the 38 – 42 weeks, when the baby is ready to be born, hormones in the woman’s blood send a message to her uterus (the place where the baby grows in his/her mother’s tummy) saying it is time for the baby’s birth.

This message causes the uterus muscles to tighten and squeeze. This is called a contraction. When the contractions are stronger and occur quickly and often, the baby is most ready to be born.
