The baby is now between 11 and 14 inches long and weighs one-and-a-quarter to one-and-a-half pounds. Quite a growth spurt in only one month! By now, your baby's features have undergone considerable refinement. His face is well defined and resembles that of a newborn. Eyelashes and eyebrows are quite distinct, although the eyelids remain closed. Other small details are also being formed this month. Fingers and toes continue to develop a newborn appearance. Fingerprints and footprints--which are unique to each individual and which will remain throughout life--are just beginning to form. Lanugo hair still covers your baby's body, but dark, coarse hair is already making its appearance on the scalp. Even though he is rapidly filling out his body, your baby's skin during his sixth month is still red and wrinkled, with very little fat beneath it. Over the next three months, more and more fat will form under the skin to eventually give baby a slightly chubby appearance. During this month, a baby's skin develops a protective covering called vernix caseosa. This whitish-yellow, cheesy substance sticks to his skin with the help of the lanugo and forms a thick barrier that protects the skin from the amniotic fluid. By the ninth month, almost all of this coating will disappear, although some babies may still have some around the creases of their arms and legs when they are born. During his sixth month, scientists believe that your baby is probably becoming aware of his environment. His tiny brain is beginning to function and his ears and eyes have developed to the point where they can sense things inside and outside your body. For example, you may become aware that your baby moves and kicks after a loud noise, such as the crash of a pan or dish hitting the floor. In some cases, you may also find that the baby stops moving in response to quiet, soothing music. It is also believed that he may actually be able to see some faint light as it passes through the walls of your abdomen and uterus. Your baby is now floating in nearly a quart of amniotic fluid. He is connected to the placenta by the umbilical cord like an astronaut in space connected to the mother ship. The clear, watery amniotic fluid serves many purposes for your developing baby. It helps to keep his body temperature normal, it provides an environment in which he can move about freely and exercise his growing muscles, and it helps to cushion him from any injury that may occur to your abdomen. Just prior to delivery, the amniotic sac will break, releasing its fluid into your vagina. In some cases, it will break on its own: in others, your doctor may purposely break it with a special instrument.
