What is happening with Caitlin? Caitlin's brain is growing rapidly at this time. Taste buds are also developing, and the lungs are becoming more developed and complex. The branches of the main lung are beginning to form as well as special cells that will produce surfactant. Surfactant is necessary for the air sacs to inflate easily. Babies who are born prematurely often have trouble breathing because these cells have not had enough time to develop or are not producing the necessary amounts of surfactant.
