At 20 weeks your baby is approximately 6.5 inches long from crown to rump, and about 10.5 inches from head to heel(about the size of a banana), and weighs approximately 10.5 ounces. (For the first 20 weeks measurements are taken from the "crown to rump". After 20 weeks measurements are taken from the head to toe.)

Your baby is swallowing more now which is good practice for digestion. It is also producing meconium, a black sticky by-product of digestion. The meconium will accumulate during pregnancy and you will see it in the baby's first dirty diaper. Also, if you feel a rhythmic jerking it is more likely to be hiccups than a kick.


Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
