36 Weeks Pregnant: Preparing for Birth

At 36 weeks pregnant, your baby is about the size of a romaine lettuce and continuing important development as birth approaches. If you are searching for 36 weeks pregnant baby size, symptoms, or development, this stage brings continued brain growth, lung maturation, and increased readiness for life outside the womb.

Your baby is nearly full term and continuing to gain strength each day.

At a Glance:
36 Weeks Pregnant
  • Baby size: about the size of a romaine lettuce
  • Trimester: third trimester
  • Key hormonal shift: relaxin continues loosening joints and ligaments as the body prepares for labor.
  • Common symptoms: strong kicks and stretches, pelvic pressure, swelling in the feet or ankles, back discomfort, heartburn, shortness of breath, and sleep discomfort.
  • Doctor visit: prenatal visits often begin weekly around this time
  • Emotional theme: attention often shifts toward preparation and readiness for birth.

At 36 weeks pregnant, your baby measures about 47 to 48 cm from head to heel and weighs around 2.7 to 3 kilograms (about 6 to 6.6 pounds).

Here is what is happening:

• the brain continues developing rapidly
• the lungs are nearing full maturity
• body fat continues building under the skin
• the baby receives antibodies from the mother that help strengthen the immune system
• the digestive system is developed but will fully activate after birth
• the skull bones remain flexible to support birth
• many babies settle into a head down position in preparation for delivery

Your baby is continuing to gain strength and coordination as birth approaches.

What Is Happening in Your Body at 36 Weeks Pregnant

As your baby grows and moves lower in the pelvis, you may begin noticing new physical sensations.

You may notice:

• increased pelvic pressure
• strong fetal movements
• swelling in the feet or ankles
• back discomfort
• heartburn or indigestion
• shortness of breath
• sleep discomfort

Some women may also notice lightening, when the baby drops lower into the pelvis, which can make breathing easier but increase pelvic pressure.

Braxton Hicks contractions may also become more noticeable as the uterus continues preparing for labor.

Emotional and Nervous System Changes

As birth approaches, many parents begin focusing more on preparation.

You may experience:

• increased awareness of your body’s signals
• a stronger focus on birth planning
• moments of emotional sensitivity or fatigue

Taking time to slow your breathing and create moments of calm can help support emotional steadiness during this stage.
