It is in week 17 that fat will begin to appear in the baby. The amount of fat is usually 5% of the total body weight and this will help in regulation of the body heat. On an average, the baby is 5 inches long and weighs 5 â 6 ounces.
At 20 weeks pregnant, baby is the size of a banana. He or she weighs about 10.2 ounces and measures about 6.5 inches from crown to rump. (Starting next week, baby will be measured from head to toe.) Baby's still got a lot of growing to do but has an excellent start!
