What Should Be Your Baby’s Weight at 31st Week?

Pregnancy is a wonderful and incredible journey for every woman, and for every parent. It is a celebration of life in its most original form. Pregnancy is a time when a woman is in touch with her body, more than ever before in her life. It is a time full of joy, pain, discomfort and expectations. Every mom-soon-to-be fears for her unborn, and wishes him or her nothing but the best, so it is very important that every mother knows everything there is to know about her growing child.

31st week of pregnancy

31st week of pregnancy is an exciting time, indeed. By now you already know your baby’s gender, and you are probably painting the walls of your nursery, accordingly. Your abdomen is getting bigger and bigger, and you feel like the baby is taking up all of the space you have inside. It is very normal for any woman to gain up to 20-30 pounds up to this point.

During your 31st week of pregnancy it is vital for your health, and the health of your baby, that you move your body as a mush as you can. Gentle exercises are always welcomed throughout pregnancy. Don’t be alarmed by shortness of breath. It’s normal.

By now, your baby can hear sounds, and you can feel your baby’s reaction and movement to sounds. Your baby can probably even react to familiar voices or singing. Also, your baby’s irises start responding to light.

At the 31st week of pregnancy, your baby’s weight should be around 2.5 – 3.5 pounds (around 1.1 – 1.6 kilograms), and it will continue to grow faster as every day goes by. Baby is about 14 – 16 inches tall, and you will start to hear those little feet kick around, more and more. That means that your baby is active, which is a very good sign.

Your baby’s weight is important because it is a great indicator and guidance for his or hers development. However, keep in mind that mom’s weight is not a good indicator of baby’s weight. Mom can gain weight, even though her baby does not, and vice versa – baby can prosper, even though baby’s mom didn’t gain that much weight.
Have in mind that every baby develops in a slightly different way. Be sure to have regular check-ups (ultrasounds and Doppler scans) with your obstetrician, and follow hers/his instructions every step of the way. Make sure that your baby’s heart and blood flow are checked every time you visit a doctor.

If your baby’s weight is small or too small (at the 31st week), it is possible that the baby doesn’t receive nutrients she needs. This can be upsetting for new moms, so it is very important to keep calm and have trust in your doctors. Reasons for small-for-dates babies are sometimes hard to detect, but these are the most obvious ones:

  • Problems with the placenta. The placenta is a link between you and your baby. This is how baby gets her oxygen and food.
  • Smoking and drinking. If you do any of these things, you should stop immediately.

Healthy pregnancy tips

There are plenty of guidelines and tips you should follow during pregnancy. Some of the guidelines can be applied during entire pregnancy, and some for a specific semester or week of pregnancy.
These are some of the healthy pregnancy tips:

  • Pay attention to your diet. Everything you eat your baby eats. Everything you drink, your baby drinks. Proper, balanced and healthy diet is the best thing you can do for your baby and for yourself. Increase your intake of protein, carbohydrates, minerals (especially calcium and iodine), organic fruits and vegetables, and last but not least – drink plenty of fresh water and fresh juices.
  • Cut down your caffeine intake.
  • When you feel tired – REST! Don’t push your limits.
  • Exercise almost every day. Take a walk, a swim or yoga class.
  • Make sure that everything is ready for the newborn baby. Your partner should be involved in this process, just as much as you are. Make sure that nursery and baby clothes are all set up. This way, when your baby comes, you will have less thing to worry about.
  • Prepare yourself mentally and emotionally for the upcoming birth.
  • Talk to your doctor, and don’t be afraid or ashamed to ask questions. Your doctor is there to help you and your baby, so make sure you go to all of your appointments. Also, be informed about your condition.


Pregnancy can be a stressful experience for a woman, but it can also be a beautiful one, full of positive changes. A healthy pregnancy is hard but possible, and once you take a first glance at your child, you will understand why you went through all that trouble.
So, eat healthy, live healthy, and your baby will be healthy too.
