Babies take in oxygen primarily through their lungs when they breathe. Air enters through the nose or mouth, travels down the trachea, and into the lungs, where oxygen is exchanged for carbon dioxide in the alveoli. Infants are often nasal breathers, which allows for more efficient breathing while feeding. Additionally, the diaphragm plays a crucial role in facilitating this process.
