Gas pains are due in part to an immature digestive system. As the baby processes the nutrients from breastmilk or formula, gas bubbles may form and get trapped in the stomach or intestines. Air bubbles can also be caused by swallowing air while nursing or drinking from a bottle, or even from excessive crying.
As the baby grows in the womb, the lungs make a special fluid. This fluid fills the baby's lungs and helps them grow. When the baby is born at term, chemicals released during labor tell the lungs to stop making this special fluid. The baby's lungs start removing or reabsorbing it.
