Pregnancy Week 11 DevelopmentHelp your baby develop in your eleventh week of pregnancy

Find out how you can fuel the growth of neurological connections taking place in your baby’s brain in week 11 of pregnancy

What's happening this week?

The major formation stage for the baby is almost complete and your baby is officially considered a fetus at this point. His or her genitalia begin forming this week, and his or her liver is now creating red blood cells in order to deliver oxygen through the bodyi.

Your baby’s brain cells are multiplying rapidly and his or her neurons and synapses are developing fast. These early neural connections allow your baby to make his or her first movements, which may not be felt by you, but can be detected by ultrasoundii.

Your baby now weighs about 8 grams and is almost two inches (5 centimeters) longiii.

What can you expect? 

Hormonal changes in your body can induce a breakout of acne on your face. Try these tips to keep breakouts at bay:

  • Wash your face twice daily with a mild cleanser and lukewarm wateriv.
  • Avoid squeezing those bumps.
  • Monitor what you eat. Certain foods may trigger or worsen acne for some peoplev.

What can you do to support your pregnancy?

Keeping a close eye on your diet is important as the blood vessels in the placenta are expanding in size and number at this pregnancy stageiv.

As the placenta passes nutrients that you consume to your babyvii, continue to have a healthy diet filled with key nutrients such as DHA, choline, folate, and ironviii,ix.

By doing this, you are supporting your baby’s brain development including the growth of neurological connections.

You could also nurture your emotional bond with your little one by talking and singing to him or her, and encouraging your partner or a close family member to do the same.
