Can you believe that you’re already at week 27 of your pregnancy?! You’ve finally entered the beginning of the third trimester! Let’s discuss your baby’s position, development, and symptoms at week 27 pregnancy — now 25 weeks from conception.
Week 27 Pregnancy: How big is your baby?
At week 27, your baby now weighs a little more than 2 pounds and is a total length of about 14 1/3 inches from head to toe (1).
The belly bump is also continuing to grow. Your uterus is about 2 3/4 inches above your belly button and 10 1/2 inches from the pubic symphysis.
Week 27 Pregnancy: Baby Position
Before 26 weeks, it’s normal for baby to be in a sideways position, known as a transverse lie. This is when the baby’s spinal column lies perpendicular to mom’s spine, with his head and feet at alternating sides of the abdomen (5).
After about 27 weeks pregnancy, the weight of the baby’s head increases and gravity gently starts to move the head downward. (Learn how to tell if baby is head down.) By 29-30 weeks, we expect baby’s spinal column to lie parallel to mom’s spine in either a head down or a breech position (4).
By around 32 weeks, the majority of breech babies will flip into the head down position. In fact, babies are head down in 97% of term births (5). This is good news because the head down position is most likely to yield a safe, uncomplicated vaginal birth.
If your baby is still transverse or breech after 32-34 weeks, discuss the situation with your doctor or midwife. Consider contacting a prenatal chiropractor skilled in the Webster’s Technique. Ask your provider about the option of an external cephalic version procedure. And learn about ways you can encourage baby to move on your own, such as the forward-leaning version or breech tilt.
Week 27 Pregnancy: Find Your Childbirth Class
Week 27 is a great time to start taking your childbirth class, or to start looking for one if you haven’t already! It’s ideal to aim to finish your natural childbirth class at least one full month before your due date. Two months before is even better if you’re able to swing it with your schedule.
Most natural childbirth classes will take at least 4 weeks to complete, although this will vary depending on the class or method of instruction. If you start at around 27 or 28 weeks, you’ll finish the class at around 32 weeks. This will leave you 2 months to practice your breathing techniques, relaxation, and other labor coping tools. And, you’ve built some wiggle room into your prep time, just in case baby comes early.

Week 27 Pregnancy: Baby’s Development
Baby is growing and developing! Some of the exciting developmental landmarks at week 27 include:
- Baby can form a smile now, especially during REM sleep
- The heart rate may decrease at the sound of familiar voices, suggesting that baby is calmed by your voice (2)
- Able to sense bright light (1)
- Baby has a strong grip
Week 27 Pregnancy: Symptoms
Stomach Muscles Separating
As baby grows, you might notice that your stomach muscles are being stretched or even pushed apart. You may even be able to see this separation down your midline when you lie down and lift up your head, as if to do a crunch. This is a result of the rectus abdominal muscles thinning, weakening, and being stretched out.
Diastasis recti is an abdominal separation of 3 or more finger widths. This may heal on its own after pregnancy. If not, there are exercises you can do after baby is born to help mend these muscles back together.
