The baby is almost 1.25 inches long. This is the beginning of the fetus period. Vital organs – primarily his kidneys, intestines, brain, and liver are formed and are starting to function. His bones are starting to form. His knees/ankles are also forming. His limbs bend, his hands flex at the wrist and meet over his heart, and his feet are long enough to meet in front of his body. His spine is clearly visible. Fingernails, toenails, and hair begin to become visible this week. The fingers are no longer webbed. His brain is now growing more quickly. Almost 250,000 new neurons are being produced every minute. He is swallowing now and starting to kick. His baby’s head comprises half the length of the body, and we will find a projection in the forehead allowing for brain development.
