The period of pregnancy is divided into three stages called trimesters (first trimester, second trimester and third trimester). Each trimester is a set of about 3 months. i.e. about 12 weeks.
A growing embryo matures slowly with the passing of time. In the first month of the first trimester- the amniotic sac forms around the growing embryo, the placenta develops, and at the end of the month, the heart is formed. The baby becomes 6-7 mm long, about the size of a grain of rice.
In the second month of the first trimester, facial features develop, tissues of the central nervous system form, digestive tract and sensory organs start developing. Buds of Limb, digits start developing and external genitalia structure starts developing. And at the end of the first trimester, the baby is almost fully formed externally. Organ and organ system develops, teeth start forming, external ears are formed.
In the second trimester, the developing foetus visual and auditory senses become functional. Taste buds develop. Hair on the head, the first movement of the foetus happens in this trimester at the end of the fifth month. Formation of eyelashes and eyelids separates in the sixth month i.e the last month of the second trimester.
In the third trimester, all organs mature rapidly. Foetus prepares for birth, it shows better motor growth. Towards the end of the pregnancy period/third-trimester foetus is positioned head down with limbs curled and finally, by parturition, the baby comes out of the mother’s womb.
Hence for a baby conceived on 1st September 2020, the taste buds and hearing abilities would develop in its second trimester i.e. between december 2020 and february 2021.
