What’s happening to your baby?

Your baby at 33 weeks pregnancy is as big as a pineapple. If you could get a peep into her brain anatomy now, you will be amazed with the busy networking of nerve connections going in and out of her little brain. Her brain is continuing to produce new cells and by birth it will reach to around 100 billion cells – that’s the number of stars on a clear night sky!

Your baby’s bones are hardening and taking their final shape except those on the top of her head. The bones on the topmost part of your baby’s head are soft and do not join yet. They make a kite-shaped gap of around 4 to 5 cm in between them. Called soft spot or fontanelle, it is designed this way to allow easy pass through of baby’s head in the birth canal during birth. The two bone plates on the top can slide over each other - called moulding – during birth. As your baby’s brain will continue to grow during the first year after birth, the soft spot facilitates the rapid expansion and doesn’t close until your baby is around 18 months of age.

She is also beginning now to develop her immune system. From now until birth, antibodies are passed from mother to the baby through placenta.

What’s happening to your body?

By now, you are almost an expert at predicting what can ail you when; how to sleep; how to walk with a load at the front, and just everything about pregnancy. If there should be something new for you to learn about your pregnant body at this stage, here it is:

·         Know how Braxton Hicks contractions and labor contractions are different: Now that Braxton Hicks are regular, get to know how they are different from true labor. Braxton Hicks can go away when you change your position and aren’t too frequent.

·         Become aware of premature labor: None of us really want it to happen. Yet, since it isn’t uncommon, learn how to identify if you are going into labor prematurely. Vaginal bleeding, contractions that do not subside, abdominal pain, water breakage and back ache are some of the common signs of premature labor.

·         Understand how to combat round ligament pain, restless leg syndrome, varicose veins, heartburn, constipation and hemorrhoids: If you’ve shrugged off all of these all these while, take time to read and ask how to get relieved from these common pregnancy symptoms. The last few weeks of your pregnancy certainly demands good amount of rest and relief.


Tips and advice for Pregnancy Week 33 Learn a relaxation technique

Relaxing yourself both before and after birthing is an art which can help you handle labor and emotions positively. With just 7 more weeks for the D-day, now is a good time to get into regular practice of a relaxation technique. Yoga, meditation, breathing exercises, aroma therapy, massaging or a healing method – choose one and practice regularly.


Studies show that women who have equipped themselves with relaxation techniques find labor unintimidating and also took lesser hours for birthing. It can free your mind from panic and anxiety as labor begins and proceeds. It helps relax your muscles and prepare your body for labor and delivery. Relaxation also increases your chances for natural birthing. Let your birthing partner join you during your classes or practice. This can help bring synchronization and coordination between you two during labor.
