At 40 weeks pregnant, you've reached the anticipated due date, and while your baby is fully developed, many pregnancies extend beyond this point.
Your body continues to support your baby with antibodies to strengthen their immune system, especially valuable if you plan to breastfeed. The vernix, a protective skin coating, has mostly worn away, which may lead to dry skin at birth.
As labor approaches, remember that your body and baby are well-prepared for the birthing process. Labor may seem daunting, but with preparation and support, many find it proceeds smoothly.
Trust your instincts, stay connected with your healthcare team, and embrace the journey ahead as you get ready to meet your little one.
Prepare for your baby's arrival with essentials from our Daily Care Collection, perfect for everyday newborn needs as you get ready to welcome your little one.
Your Baby At 40 Weeks
At 40 weeks, your baby is about the size of a small pumpkin, weighing around 6 to 9 pounds and measuring 19 to 22 inches long.
Hands and Feet Position
With fully formed hands and feet, your baby’s limbs are now flexed in a fetal position, often head-down, as they prepare for birth.
Facial Features and Skin
Your baby’s face is well-defined, with most of the protective vernix now gone, leaving skin that may appear slightly dry. Some babies may still have traces of lanugo, a fine hair that once provided warmth.
Organ Maturity
All major organs are fully developed and ready for independent function. The heart pumps blood throughout the body, and the lungs are prepared for that first breath, though they may need a brief adjustment to life outside the womb.
Sensory Awareness
At this stage, your baby can recognize familiar voices, including yours, which supports early bonding. They may also react to light changes through the womb, showing an active sensory response as they prepare for the outside world.
Umbilical Cord and Birth Transition
The umbilical cord, which supplied nutrients and oxygen throughout pregnancy, will be clamped after birth as your baby transitions to independent breathing and feeding.

Your Body At 40 Weeks Pregnant
At 40 weeks, your body is fully engaged in the final stages of preparation for labor. Here’s what to expect as you approach this important milestone:
Pelvic Pressure and Baby Dropping
As your baby settles lower into the pelvis, or “drops,” in preparation for birth, you may feel increased pressure in the lower abdomen and pelvis. This shift helps the baby position for delivery and can lead to more frequent bathroom trips as your baby’s head presses on your bladder.
Cervical Changes
As labor nears, your cervix may begin to thin (efface) and open (dilate) in preparation for delivery. This process varies for everyone, with some people experiencing gradual changes over weeks and others noticing them closer to labor. Healthcare providers often monitor these changes during check-ups.
Weight Distribution and Balance
With your baby now fully developed, the added weight may shift your center of gravity, making balance a bit challenging. This change can impact your posture and balance, so being mindful of supportive footwear and using assistance when needed can be helpful.
Braxton Hicks Contractions
Practice contractions, known as Braxton Hicks, may feel stronger and more frequent as your body prepares for labor. While typically irregular and mild, these contractions help your uterus get ready. If they start to feel more regular, contacting your healthcare provider is recommended.
These final body changes signal that your body is preparing for labor and delivery. Staying hydrated, resting, and listening to your body’s cues can provide support as you approach your baby’s arrival.
Pregnancy Symptoms At 40 Weeks
At 40 weeks, the final days of pregnancy can bring a range of symptoms as your body prepares for labor. Here’s what to expect as you approach your due date:
Contractions
You may experience Braxton Hicks contractions, which are generally mild, irregular practice contractions that prepare your uterus for labor. These contractions can sometimes be confused with real labor, but true labor contractions are typically stronger, regular, and grow progressively closer together.
Pelvic Pressure
With your baby settling lower into your pelvis, you may feel increased pelvic pressure, a process called “lightening.” This pressure often causes discomfort and can affect your center of gravity as your body prepares for delivery.
Loss of Mucus Plug
As labor approaches, you may lose your mucus plug, a protective barrier that sealed your cervix during pregnancy. This can be accompanied by a “bloody show,” which is a small amount of blood in the discharge, and is a common sign that labor is near.
Water Breaking
Water breaking occurs when the amniotic sac ruptures, releasing amniotic fluid. This may present as a sudden gush or a slow leak. If you experience this, contact your healthcare provider, as it generally indicates that labor will soon follow.
Insomnia
Difficulty sleeping is common at this stage, often due to physical discomfort and anticipation of labor. Focusing on rest, even if full sleep is elusive, and finding comfortable positions can help you manage this symptom.
As your body prepares for delivery, staying in touch with your healthcare provider is essential, especially if you experience any concerning symptoms.

Tips For A Healthy Pregnancy At 40 Weeks
As you reach the 40-week mark, it’s essential to feel prepared and comfortable. With delivery close, having everything in order can help ease stress and keep you focused. Here are a few practical steps to consider:
Pack Your Hospital Bag
Include comfortable clothing, toiletries, postpartum supplies, and essentials like ID, insurance information, and necessary paperwork. A prepared hospital bag ensures you have everything you need when it’s time to go.
Discuss Delivery Options
Talking with your healthcare provider about delivery possibilities, like a c-section or episiotomy, can provide clarity. Understanding potential options will give you peace of mind as you head into labor.
Labor Pain Management Techniques
- Breathing Exercises: Practice breathing techniques to help manage pain and stay calm.
- Hydrotherapy: A warm bath or shower can soothe contractions and relieve tension.
- Raspberry Leaf Tea: Believed by some to tone the uterus, it may ease labor, though it’s best to check with your provider before use.
Inducing Labor
- Nipple Stimulation: Gently stimulating the nipples releases oxytocin, which can help bring on contractions naturally.
- Light Activity: Staying active with gentle walks helps maintain circulation and may encourage your baby to shift into position for birth.
Plan for Pain Relief
Discuss options like an epidural with your doctor to decide on the best pain management strategy for you.
Prepare for Breastfeeding and Recovery
If you’re considering breastfeeding, starting early provides your baby with essential antibodies. Breastfeeding also promotes contractions that help your uterus return to pre-pregnancy size.
Postpartum Essentials
Stock up on postpartum pads and comfortable clothing. Having these essentials on hand can make recovery smoother and keep you focused on bonding with your baby.
