21 weeks pregnant: your baby

week 21

Your baby at 21 weeks of pregnancy

During the twenty-first week of pregnancy your baby can measure over 7 in./17 cm. and weighs about 10.5 oz./300 g. We know we haven’t given you a fruit reference in a while but here’s one now, you baby is about the size of a large banana!

Your baby’s organ systems are maturing and as a result he is steadily growing. This week your baby’s digestive system is beginning to function as your baby drinks the amniotic fluid that surrounds him. Amniotic fluid contains some of the important calories and nutrients your baby needs, the rest he will get from the placenta. Are you wondering what amniotic fluid tastes like? Well think about what you’ve eaten today and that is exactly what it tastes like.

Did you know…your baby can drink up to 17 oz. of amniotic fluid each day?
