Baby's development - 21st week

Your baby is putting on a lot of weight at the moment. The amniotic sac contains 400 ml of liquid and your baby is very comfortable to move as he pleases and you can feel this gymnastic quite well. He is also getting used to cycles of wake and sleep that will become more obvious to you as your pregnancy evolves. He can be very active during the evening… when you would like to sleep.

This week
