Your baby now weighs around 2.5 pounds / 1.1 kilograms and measures about 15 inches / 38 centimetres from head to toe. In boys, testicles descend from near the kidneys through the groin en route to the scrotum. In girls, the clitoris is relatively prominent because it's not yet covered by the still-small labia. These will grow to cover it in the last few weeks before birth.

Your baby's head is getting bigger, and brain growth is very rapid at this time. Nearly all babies react to sound by 30 weeks.

Your baby's nutritional needs reach their peak during the third trimester. You'll need plenty of protein, vitamin C, folic acid, iron, and calcium (about 200 milligrams is deposited in your baby's skeleton every day), so eat foods rich in these nutrients. The skeleton hardens even more and the brain, muscles, and lungs continue to mature. So take a look at our eating well guide to make sure you are getting the right minerals and vitamins.
