Pregnancy Calendar Week 30

It's perfectly normal to feel some mood instability during week 30 of your pregnancy. Understanding where these feelings come from and using some relaxation techniques to cope can help you enjoy this portion of your pregnancy.

Your Baby's Development

By week 30, your baby is almost three pounds and measures about 15.7 inches from head to toe. According to the Mayo Clinic, he is also experiencing the following developments this week:

  • Although your baby has had his eyes open for a couple of weeks, during week 30, your little one's eyes are now open wide.
  • At this point in your pregnancy, your baby's bone marrow is now capable of red blood cell production. Red blood cells deliver oxygen, and remove waste from the body.
  • He may also have developed a nice amount of hair by this point in your pregnancy.

Your Changing Body

The American Pregnancy Association reports that mood swings are quite common during the third trimester as your hormone levels continue to fluctuate. Since mood swings can be aggravated by fatigue, make it a priority to get the rest you need. Ask your partner for help with household chores, hire a sitter to give you a break from your older children, and try to avoid working late at the office.

During week 30, you may notice colostrum leaking from your nipples. This is your body's way of preparing for breastfeeding. It's not a cause for concern, and the substance can be easily absorbed by wearing breast pads inside your bra.

More to Know About Week 30 of Your Pregnancy


If you're feeling tense, you may want to consider learning more about various relaxation techniques. In addition to helping you cope with your feelings about your baby's impending arrival, relaxation techniques can be used to provide natural pain relief during labor. While prenatal yoga is one of the most popular ways to promote relaxation, many other exercises can help you learn to regulate your emotional state better.

One basic physical relaxation technique requires that you lay down in a comfortable position. Then, simply close your eyes and concentrate on alternately tensing and relaxing the various parts of your body. Begin with your toes and work your way up to the top of your body.

Mental relaxation techniques focus more on clearing your mind. To practice this form of relaxation, sit in a comfortable position and concentrate on following the pattern of your breathing. Try to empty your mind of any unpleasant thoughts. Breathe in deeply through your nose and exhale slowly through your mouth until you feel completely relaxed.
