The baby weighs 2.4 kilograms and 18.5 inches from head to toe. The wall of your uterus/abdomen become thinner and let in more light; this allows your baby to develop daily activity cycles. He has a fully developed pair of kidneys, and his liver can process some waste. The amniotic fluid in your uterus has reduced significantly.
The baby continues to accumulate fat all over his body, especially around the shoulders. His most rapid period of weight gain will occur over the next three weeks. Given his size, you may feel fewer of your baby’s movements this week. You’ll probably feel stretches, rolls and wiggles rather than jabs and kicks.
By now, he would have shed most of his lanugo hair. Your baby’s neural connections develop at a rapid pace, and his skull remains pliable. If he is in a head-first position, his head will rest on your pubic bone in preparation for labor.
