The pregnancy period is broadly divided into three trimesters. The first trimester begins from the first week and continues till the 12th week. The second trimester has its duration from 12 to 24 weeks and the second trimester goes from 24 to 40 weeks. But the development of the baby occurs in every week. However there is a need to look at the period for each respective month.
During the forth month the baby continues to grow, toe and fingernails appear and fine hair appears all over the body. The muscles develop further, and the baby's movements as it swims and kicks are more coordinated. Now the fetus is about 14cm in length. Further development takes place, the eyebrows and eyelashes have emerged the tongue has developed taste buds. Your little angel should now be able to curl their fingers and toes and suck their thumb. An ultrasound is commonly taken on the 18 week to determine position of placenta, multiple pregnancy and abnormalities if any. A Routine “maternal serum screening” is done during this time to help check the risk of having a baby with a birth defect. Amazingly, the fetus often gets hiccoughs. |
