How Big is Your Baby at 31 Weeks Pregnant?

At 31 weeks pregnant, your baby is the size of a coconut. They weigh around 3.3 pounds and are approximately 16.2 inches long. That’s quite a bit bigger than they were just a few weeks ago!

31 Weeks Pregnant Baby Development: What’s Happening?

Your baby is continuing to mature and develop at a rapid pace. Here are some of the key things happening during 31 weeks pregnant baby development.

Lungs

The lungs are nearly fully developed at this point, which means that your baby could potentially breathe on their own if they were born prematurely. However, their lungs will continue to mature right up until birth.

Brain

Your baby’s brain is growing quickly, and they are becoming much more aware of their surroundings. They can now regulate their own body temperature and are starting to develop their own sleep-wake cycle.

Bones

Your baby’s bones are hardening, but they are still relatively soft and pliable. This flexibility will make it easier for them to pass through the birth canal when the time comes.

What You Might Be Feeling at 31 Weeks Pregnant

As your baby continues to grow and develop, you may be experiencing some discomfort and other symptoms. Here are some of the most common things women report feeling at 31 weeks pregnant.

Braxton Hicks Contractions

You may be experiencing Braxton Hicks contractions at this point. These are essentially “practice” contractions that help your uterus prepare for labor. They can be uncomfortable, but they shouldn’t be too painful.

Shortness of Breath

As your baby grows and your uterus expands, you may find that you are feeling short of breath more often. This is normal, but if it becomes severe, be sure to talk to your doctor.

Heartburn

Heartburn is common during pregnancy, and it can be especially bad in the third trimester. Try eating smaller meals throughout the day and avoiding spicy or acidic foods.

What You Can Do to Support Your 31 Weeks Pregnant Baby Development

There are a few things you can do to help support your baby’s growth and development during this stage of pregnancy.

Your baby needs nutrients to grow and develop properly, so be sure to eat a healthy, balanced diet. Focus on nutrient-dense foods like fruits, vegetables, lean proteins, and whole grains.

Stay Active

Staying active can help support your baby’s growth and development as well as help you feel better physically and emotionally. Talk to your doctor about what types of exercise are safe for you during pregnancy.

Get Plenty of Rest

Sleep is crucial during pregnancy, so be sure to get plenty of rest. Aim for 7-9 hours of sleep each night, and consider taking naps during the day if you need to.
