The baby is moving about vigorously and responds to touch and sound. A very loud noise may make him or her jump and kick, and you’ll be able to feel this.
Your baby is regularly passing urine into the amniotic fluid. Sometimes the baby may get hiccups and you can feel the jerk of each hiccup.
The baby’s eyelids open for the first time and he or she will soon start blinking. The eyes are almost always blue or dark blue, although some babies do have brown eyes at birth. It’s not until some weeks after the birth that your baby’s eyes become the color that they will stay. You can find out more about your baby after birth.
By now your baby’s heart rate will have changed to around 140 beats per minute. This is still considerably faster than your own heart rate.
Your baby’s brain, lungs, and digestive system are formed but not fully mature — they’ll spend the rest of your pregnancy developing so that they work properly when your baby is born.
By 28 weeks, your baby weighs around 1kg and is perfectly formed. The baby’s heartbeat can now be heard through a stethoscope. Your partner may even be able to hear it by putting an ear to your abdomen, but it can be difficult to find the right place.
Your baby continues to put on weight as more and more fat appears under the skin.
