Pregnancy Week 18 DevelopmentHelp your baby develop in the eighteenth week of your pregnancy

Your baby’s bones are growing stronger and are hardening. Eat more calcium-rich foods to strengthen your baby’s bones further.

What’s happening this week?

Incredibly, your little one now has developed his or her unique fingerprintsi. Also, his or her bones are growing stronger and are hardening.

In terms of brain development this week, connections between nerve cells in the brain stem and spinal cord are forming, and will help to refine your baby’s movements and reflexes, like having a firm hand grip.

This week, your baby’s hearing is also developing. This means that the bone in his or her inner ear is forming along with nerve endings that will allow him or her to hear what’s aroundii, like the rumbles in your tummy… and your voice!

Baby is about seven ounces (almost 200 grams) in weight now and is around five and half inches (14 centimeters) longiii.

What can you expect? 

Some Mums-to-be may get sudden nosebleeds at this pregnancy stageiv, due to increased blood flow during pregnancy. Avoid nosebleeds and enjoy your pregnancy with these tips:

  • Stay hydrated. Drinking more water can prevent your nose membranes from getting dry, which makes it easier for the delicate vessels in the nose to break and bleed.
  • Stay away from environmental irritants such as smoke.

What can you do to support your pregnancy?

By continuing to eat more calcium-rich foods this week, you’ll be helping your baby’s bones grow strongv. Foods that contain DHAvi remain important to support your little one’s brain development.

Remember that from healthy brain growth stems from good emotional development, as the brain is the center for emotions and their regulation, alongside its cognitive functions, such as reasoning, problem solving, and memory.

This applies to you too, mom-to-be. When you are stressed or anxious, your brain signals your body to release stress hormones such as cortisolvii. If the levels of these ‘stress hormones’ are consistently high, it could have negative health effects on your baby, according to prenatal health expertsviii.

If you’re overwhelmed with having to deal with new symptoms and your changing body, talk to your doctor, a friend, your partner, or a family member about how you feel to get some support

You could also try relaxation techniques such as controlled breathing, meditation, or simply engaging in activities that you know help you relax.
