How developed is the baby at 8 Months Pregnant?

Bone Development almost Finished

8 months pregnant

Muscles are developed, the brain is still growing larger, the nervous system has almost completely matured and the bones are now almost fully formed. Now that the fetus is growing larger and with a full amount of amniotic fluid, the space in your tummy is becoming cramped and you begin to feel clumsy. Your baby is gaining weight which is smoothing out many of the wrinkles in their skin. The baby can adjust its own body temperature and starts to practice breathing. If you go into early labor now, the chances of the baby surviving are very high.

The Senses are Developing

Continuously developing, the sense of hearing is now fully developed. The baby can now hear everything going on around them outside the tummy and loud noises may even make them jump! You can continue performing brain training or prenatal education during this time. The babies sight is developing quickly now and the baby is capable of tracking strong light. After 27 weeks, the pupil is fully developed and the baby is trying to focus. Most importantly, the baby can detect its mothers feeling and will know if its mother is happy or sad.

Babies Head starts descending into your Pelvis

In preparation for birth, the baby’s head will start to turn towards the pubic bone. Some babies will still be in a head up position, but don’t worry; the baby still has time to turn around, as some babies won't turn their heads down until the last month. Even though the baby has not turned at this stage, it is not necessary to worry unless the umbilical cord is too short or the amniotic fluid is insufficient.

Using Thoracic Diaphragm to Practice Breathing

The baby is receiving oxygen through the umbilical cord attached to the placenta so before they are born, they are not breathing as we do. Now they are practicing breathing using thoracic diaphragm to ready themselves to breathe independently after birth.

Changes in Mommy’s Body

At 8 months pregnant, the fundal height is now 25 to 28cm, your tummy feels very big now and you are getting bigger and bigger every day. Now, you will waddle around and your belly button may have popped out. Avoid long periods of standing as this may lead to early contractions and will make your tummy feel tight and uncomfortable.

Your back and waist may start to feel painful. You might start to retain water in your legs and your face may become puffy. You may experience leg cramps now and tiredness is very common.

Now that the uterus is getting higher and higher and pushing everything in its path, it will become increasingly difficult to breathe. Most of your internal organs will now feel discomfort particularly your heart and your stomach and getting a good night sleep will become increasingly difficult.

Checkups for this Month


The ultrasound can tell you how much amniotic fluid you have, the position of the placenta and the size of the baby and its position. It’s important to monitor the amount of amniotic fluid as well as the baby's size as these could indicate problems.

Reading Fairy Tales Happily for your Baby

The baby’s neural cells are rapidly developing, memory starts to improve, hearing is now fully functional and the baby can easily distinguish sounds. The baby can detect the stress in your voice and tell if you are in a good or bad mood. Your baby will also react to the different voices within your home as the baby can now recognize family member’s voices.

When you read stories or fairy tales to your unborn baby, its better that you speak with emotion. Whatever mommy reads, listens to and feels is all a part of the prenatal training process. So it's better for the baby if mommy embraces happiness and maintains a positive mood.

What Moms need to Know: How to get a better Sleep

Sleep on your left side

Try and sleep on your left side while bending your bottom leg. Resting your tummy on the bed will give you and the baby a stable and secure feeling. You can also snuggle up with a pillow to give you more support. If your tummy is not that big, you can place the pillow between your legs. If you are suffering from swollen legs, try sleeping on your side and raise your legs a little by placing a pillow under them to help blood flow and relieve tiredness. Sleeping on your left side is also good for your blood circulation and helps blood flow through the uterus and support the baby. It also promotes better kidney function, cleaning out more waste from your body.

Avoid sleeping on your tummy and lying on your back

Try to avoid sleeping on your tummy during your pregnancy as this is known to be bad for the baby and the mommy. Lying on your back is preferred if you can't lay on your side during early pregnancy, but not advisable for the last trimester due to the fact that the heavy uterus will press down on your spine and block your blood circulation.

Using pillows

Try to support your waist and belly with pillows. Using pillows for support can ease your discomfort while sleeping and also help to improve the quality of sleep. You can put pillows between your legs and use pillows to support your waist. Pregnancy pillows are designed for this job and are best for alleviating discomfort.

Do exercise 3-4 hours before going to bed

It is recommended to do some light exercise during pregnancy, but you need to avoid doing any forms of exercise just before going to bed as this will seriously affect your sleep. Performing an exercise 3-4 hours before sleep will actually help give you a better night sleep.

Take naps during the day

Taking regular 30 minutes to 1 hour naps will not only help improve your focus but also your memory and relieve tiredness. But be warned to only keep your naps short as sleeping for long durations during the day will make falling asleep at night very difficult. So keep the naps short and enjoy a better energized you.

Regulate your sleeping time

After a lovely dinner, relax with a book then take a shower after doing some light gentle exercises. It's important to regulate your sleeping time to ensure you’ll have a better sleep.

If you can’t sleep then its better just to get up

If you still can’t fall asleep 20 to 30 minutes after you went to bed, then maybe it's better just to get up, go to another room, listen to some music, read a magazine and then go to bed when you feel tired.

That’s all the pertinent information you need to know during 8 months pregnant.
