Baby in Breech Position

The short answer

A breech presentation means the baby is positioned bottom-first or feet-first rather than head-down. About 3-4% of babies are breech at full term. Many babies turn head-down on their own before 36-37 weeks. If the baby remains breech, options include external cephalic version (ECV) to turn the baby or a planned cesarean delivery.

Thousands of parents search for this exact thing. You are not alone.

By Age

What to expect by age

It is very common for babies to be in breech position in the second trimester. At this stage, there is plenty of room for the baby to move and turn. Most babies will naturally move to a head-down position by 32-36 weeks. There is no need to worry about breech position before 36 weeks.

If your baby is still breech at 36 weeks, your provider may discuss ECV - a procedure where the provider manually turns the baby from the outside. ECV is successful about 50-60% of the time and is performed in a hospital setting. Some people also try positioning techniques (like hands-and-knees position) or complementary therapies, though evidence for these is limited.

If the baby remains breech, a planned cesarean at 39 weeks is the most common delivery approach in the US. Vaginal breech delivery is an option at some hospitals with experienced providers but is not widely available. Discuss your options and preferences with your provider.

What Should You Do?

When to take action

Probably normal when...
  • Baby is breech before 36 weeks - this is very common and most will turn
  • Feeling kicks low and pressure high (baby's head in your ribs)
Mention at your next visit when...
  • Baby is still breech at or after 36 weeks
  • You want to discuss ECV or other options for turning the baby
  • You want to explore vaginal breech delivery options
Act now when...
  • Water breaks with a breech baby - go to the hospital immediately (risk of cord prolapse)
  • Labor begins with a known breech presentation

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

Baby Lying Sideways (Transverse Lie)

A transverse lie means the baby is lying sideways (horizontally) across the uterus rather than vertically. This is common earlier in pregnancy but occurs in less than 1% of pregnancies at term. If the baby remains transverse near your due date, your provider will discuss options including external cephalic version (ECV) or planned cesarean delivery, as vaginal birth is not possible in this position.

When Birth Does Not Go as Planned

It is very common for birth to unfold differently than planned. About 1 in 3 births in the US involve cesarean delivery, and many other births involve unplanned interventions. Feeling disappointed, sad, or even grieving the birth experience you envisioned is completely valid. What matters most is that you and your baby are safe, but your feelings about the experience also matter.

Dealing with Abnormal Prenatal Screening Results

An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.

Pregnancy Over 35 (Advanced Maternal Age)

While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.

Amniocentesis Questions and Fears

Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.

20-Week Anatomy Scan Unexpected Findings

The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
