Week 27 Pregnancy Baby Position & Symptoms

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).

Your belly bump is also continuing to grow. Your uterus reaches about 2 3/4 inches above your belly button, or 10 1/2 inches from the pubic symphysis or pubic bone.

Week 27 Pregnancy: Baby’s Development

Baby is growing and developing quickly as you begin the third trimester! Some of the exciting developmental landmarks at week 27 include:

Week 27 Pregnancy Development
  • Baby can form a smile now, especially during REM sleep
  • Little one’s heart rate may decrease at the sound of familiar voices, suggesting that baby is calmed by your voice (2)
  • Baby is able to sense bright light (1)
  • His or her little hands have a strong grip

Week 27 Pregnancy: Baby’s Position

week 27 baby position transverse vs head down

Transverse Lie

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 spine lies perpendicular to mom’s spine, with his head at one side of mom’s abdomen and his feet on the other side (5).

Head Down or Breech

After about week 27 of your pregnancy, the weight of the baby’s head increases and gravity gently starts to move the head downward. 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 result in a safe, uncomplicated vaginal birth.

Turning Baby to a Head Down Position

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, which helps align your pelvis to aid in baby getting into an optimal position. Ask your provider about the option of an external cephalic version procedure, where the provider attempts to manually turn the baby to a heads down position. 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 Pregnancy Ideal Time for Childbirth Class

Week 27 is an ideal time to begin taking your childbirth classes, or to find one if you haven’t already! The goal is 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.

Leave Enough Time To Prepare

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. You’ve also built some wiggle room into your prep time, just in case baby comes early.

Week 27 Pregnancy: Symptoms

Stomach Muscles Separating

As baby grows, you might notice that your stomach muscles are being stretched or feel a separation between the right and left abs that run down your stomach. You may even be able to see this separation down your midline when you lie down and lift up your head, as if you’re doing 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.
