Baby development at week 21

The baby can taste flavours from your diet through the amniotic fluid. Movements are becoming more coordinated and you are likely feeling regular kicks and shifts. The digestive system is maturing and the baby swallows amniotic fluid regularly. Eyebrows and eyelashes are forming. The baby weighs about 360g.

Your body this week

Your bump is growing steadily. Stretch marks may appear on your abdomen, breasts, or thighs. Varicose veins can develop due to increased blood volume and pressure. You may notice swelling in your hands and feet, especially later in the day. Backache is common as your posture adjusts to the growing bump.

Things to do this week

1
Stay active with gentle exercise
2
Moisturise your skin if it feels itchy or tight
3
Start thinking about what baby items you need to research

Frequently asked questions

Can my baby taste what I eat?

Yes, from around week 21. Flavours from your diet pass into the amniotic fluid. Research suggests that babies who are exposed to a variety of flavours in the womb may be more accepting of different foods after birth.
