Why do I have a belly button ?????

For the same reason dolphins, cats, dogs, chimps, bats, and other " placental mammals"- animals nourished inside their mothers before birth- have navels. In other words, you can thank you are a mother for that link connector on your stomach. Before you were born, when you were still developing in the womb, you were hooked up to your life - support system through a special cord that plugged into your navel. Through this" umbilical cord"- you received food and oxygen and past waste. The day you were born, you let out a cry and begin breathing on your own. That let the doctor know he or she could cut off the umbilical cord, leaving you with a belly button as a Souvenir. Whether it's an"innie" or an "outie" we all have one!
