20 Weeks- Development

Your Baby This Coming Week

Your baby weighs about 10.5 ounces (300g) and measures about 7.2 inches (18cm) from crown to rump. He still moves about freely in amniotic fluid.

Your baby may respond to external sounds, such as the music you are listening to or your voice.

Your baby has developed some red blood cells already. The white blood cells that your baby needs to fight infections are being manufactured.

He is developing taste buds on his tongue.

His digestive system is sufficiently advanced to absorb water and sugar from the amniotic fluid that he swallows and pass it to his large bowel.

Your baby has lanugo hair on his forehead and upper lip and his eyebrows are thickening.

Vernix (the waxy substance that covers and protects your baby's skin) accumulates on your baby's eyebrows.

Your baby's eyes are still sealed shut.

Your baby continues to grow and develop and his kicking is getting stronger now.

Your Body This Coming Week

In the next ten weeks your weight gain will increase more rapidly as your baby grows and develops layers of fat. This is when you will gain about half of your total pregnancy weight.

You need to eat about 500 more calories per day now to support you and your baby. You will probably notice an increase in appetite during this time to keep pace with your increased needs and metabolism.

Try to avoid unhealthy snacks and try to choose snacks with the most nutritional value for you and your baby. You may experience uncommon cravings. A pregnancy condition known as pica, causes some women crave eating things that are not even edible (such as soil).

Your skin may itch. This is because it has stretched to accommodate your growing abdomen.

The top of your uterus has risen further and is now parallel with your belly button, probably making your belly button flat.

Your lower legs may be swelling somewhat, though this is improved when you are able to stay off your feet for part of the day.

You may experience heartburn or indigestion. Many antacid tablets are safe to take during pregnancy, but check with your doctor or pharmacist first.
