By  | 

“A baby is something you carry inside you for nine months, in your arms for three years, and in your heart until the day you die.” –Mary Mason

Who once used to keep you up at nights now snores away with you. The one who used to make you feel like your emotions are overflowing now shares a bite into your humble food and breathes through you. The fetus now grown and strong inside you rumbles around letting you know he is ready for the world.

The subtle kicks depict his discomfort in a cramped place and so on another week rolls by. Usually in medical terms ,the entire pregnancy process due to medical assistance is summed up in week instead of months, this way frequent monitoring of your young one is possible. The entire of the 40 weeks is what sums up the nine months and in your 31st week the baby’s changes can be recorded in the ultrasound.

31 Weeks of Pregnancy

Fetal Development of the Baby:

Change in Movements:

Until a certain point of time, the baby has no sense to reciprocate on but with the days ageing in the baby’s sense starts growing. Slow and steady he recognizes the surrounding he is in. he recognizes the factors keeping him alive, his body masters the art of normal human body functions. This all piles up to the point where he can work on his own. Now his muscles stabilize and he can move them at will. This is when the movements start. The initial stage records the baby tumbling around rolling by but by the 31st week the movements change. The baby now starts kicks and punches letting the mother know he feels cramped in the place.

Hearing Aid:

The hearing aid that is the ear is now working in full form receiving noise and changing it to sense as the brain impulses kick up to work full speed on it. A human ear can only decode a sound when not only the ear elements work together but also when the impulse heard or received can be perceived and decoded by the brain. By the 31st week, the brain has already started taking up the proper shape and now can receive impulses and work on it. This is why your baby’s audible detection of your voice and surrounding may not be a surprise to you. She can now hear your voice, any specific music or stories that you read.

Double Himself:

By now your baby weighs a good 3.5 pounds and with his growth spurt ending, he now measures up to an 18 inch give or take. Half of this weight belongs to the now fat layers growing underneath the skin. The arms now start to take up a chubby shape along with the gut and thighs. The amniotic fluid in which your baby was afloat all this time now begins to reduce itself to provide more space for the growing baby.

Involuntary Actions:

In the 31st week, the baby’s reflex actions have taken up a broad range. The ultrasound now not only reveals his hearing capability loud and clear but the doctor’s say if you flash a bright light right in the middle of the belly button your baby just might respond to it by either moving his head away or towards the light. By now those flittering little peepers have somewhat gotten used to the sensitivity of light. The other reflex action now involves yawning which can be noticed if lucky by catching a moment of it in the ultrasound. He may even have his favorite sleeping position that might be clear this week. These subtle actions this week will prepare your baby for the outside world.

Breathe Away:

With time the baby’s lungs are developing more and more. this is not a one day work and would require some time but be assured by the end of this week he would have a sound lung expanding and contracting to the now red blood cells produced by none other than himself. The lungs maturing slowly also helps the trachea or the wind pipe to open up so that baby no longer requires the mother’s umbilical cord to pass in oxygen and breathe out carbon di oxide.


The food and oxygen supply from the mother through placenta is doing the work for the fetus heart to function.Later of the birth the work is taken care by the lungs of the baby.During the third week of the fetus growth the heart starts to beat and by 30th week the baby is already on the pelvic floor for coming into the world.

Symptoms of 31stWeek Pregnancy and How to Overcome:

The entire of the 40 weeks explained prior to this is further segregated into three stages. The first trimester when the mother has to yet get used to the changes rapidly occurring in her body. The next trimester is referred to as the golden trimester where the baby and the mother forms an understanding well enough. The third trimester, the 31st week considered in it again sees the problems reoccurring.

Back Pain:

Right about now you would feel a sharp pain shooting down your spine right in the middle of the night. You would wake up with a jolt and lie down for hours trying to make the pain go away but as long as you are on your back it never will. This is because with the baby growing inside the space he requires slowly closes in on him. As a result when you are laid down on your back, he pushes around for more space and eventually pushes your spines back to accommodate for him. Avoid this by sleeping on your side.To overcome this uneasiness, try sitting up straight, as this restricts the movement of your baby. However, do not do this all the time, since this hampers his play time inside your womb.

Subsidiary Problems:

The usual problems on the first weeks of the pregnancy will be back now. The frequent urination is back along with faulty bowel movements. Never before have you woken up at four in the night to rush to the bathroom but now you just might. Besides this the sorry appetite of yours might give way to indigestion or heart burn which is due to the over production of female hormones messing with the other body hormones.One way to overcome this situation is limit your liquid intake like coffee ,tea and sugary drinks.

Mask of Pregnancy:

While some glow in glory for most of us, the shining scarf of pregnancy might not be flawless. The usual of us experiences a mask of pregnancy that masks our face along with irrelevant body parts. The back acne, the stretch marks are just a side effect of the brown blotches or freckles your face sports now. This too is to be blamed on the female hormones which would subside once the 40 weeks are over.Aloe Vera is your friend now, and you need it for a favorable experience with your skin. Of course it does not solve your marks, but most certainly works on the way of reducing it.
