Your baby measures almost 2/3 of an inch now. Your baby’s hands and feet develop webbed toes/fingers; his eyelids are almost formed and cover his eyes, breathing tubes are forming from his throat to his developing lungs. He does not have a tail anymore. His brain is forming and nerve cells connect with each another, forming neural pathways. The external genitals are not yet developed enough to determine your baby’s sex. His heart beats at 150 to 170 beats per minute. The baby is starting to move, and his digs are getting bigger. His taste buds are now forming. Your baby’s digestive tract is growing (especially the intestines). His heart and blood circulation are now more fully developed.
