40 Weeks Pregnant
Your 40th week begins
- Development The lungs are now mature and as soon as the umbilical cord is cut, baby will start breathing on their own.
- Agenda Watch for signs of labor, and as soon as you notice contractions, time them to see the interval between each one.
- How many months is 40 weeks? 40 weeks pregnant is 9 months. With week 40 of pregnancy, you are in the final week of your 9th month of pregnancy.
IMPORTANT: Have you decided to use a postpartum girdle? Choose the right models and never buy a size smaller than what you usually wear. Wearing a girdle that is too tight can have the opposite effect and even be harmful to the new mom’s recovery.
IMPORTANT: If the maternity hospital where you are having your baby allows you to have an accompanying person, don’t forget to pack your partner’s bag. After all, he will also need to shower, change, and brush his teeth. Enjoy every minute of this moment because it is unforgettable!
- At 40 weeks pregnant your baby is already ready to come into the world, just waiting for the green light from the hormones to make their appearance!
- After birth, they will still be able to see about 30 cm (12 inches) from your face, which is about the distance to mom’s face while breastfeeding.
- Tiredness sums up the mother at 39 weeks pregnant!! Exhaustion and reaching your limit are obvious since the belly is so big and it’s hard to sleep well, walk properly or even do everyday tasks.
- If there is no medical recommendation against it, try to maintain intimacy frequently.
- All you need now at 40 weeks of pregnancy is to remain calm and peaceful so you can have a smooth delivery and enjoy your baby’s arrival.
More information about 40 weeks pregnant
At 40 weeks pregnant, your baby is already ready to come into the world. It’s just waiting for the green light from hormones to make its debut! With fetal development now complete, your baby is getting ready to finally meet this world! Their whole body is fully developed, including internal organs, which are already functioning as expected. All their senses are active and respond to stimuli, and in time, each one will adapt and improve even more. Your baby’s little heart beats quickly1, around 110 to 160 beats per minute.
At 40 weeks of pregnancy, your baby’s respiratory system, which had been maturing in recent weeks, is now ready2. As soon as the umbilical cord is cut, the baby will begin to breathe on their own. Your baby’s eyes, which were used to seeing only a short distance inside the womb, now have to adjust to seeing things farther away. After birth, they will still be able to see about 30 cm (12 inches) from your face, which is about the same distance as mom’s face during breastfeeding.
Each baby is born with a different weight and length, but at 40 weeks it is normal and expected for a baby to weigh an average of 3.4 kg (7.5 lbs) and measure 51 cm (20 inches). All their bones are now firm and strong except for their skull, which has not yet closed to make it easier to pass through the birth canal.
How mom is feeling
Tiredness sums up how moms feel at 40 weeks! Exhaustion and reaching their limits are evident. Your bump is really big, making it hard to sleep well, walk normally, or even do simple everyday tasks. To make things worse, the anxiety can be so intense it even takes away your appetite! But there’s nothing to do except wait for your body to react and show you that the time has come. It’s nearly time, and it could happen at any moment now.
If at 40 weeks pregnant your contractions are still only coming occasionally, you can start going for walks. Walking helps speed up labor, and the expectant mom can walk for about an hour a day, but it’s important to choose a time when the sun isn’t too intense. Remember, pregnancy can last up to 41 weeks. But if things don’t progress, it’s very common for the doctor to induce labor or schedule a cesarean section.
If there is no medical recommendation against sexual activity3, try to be intimate as much as possible. Sexual intercourse can help speed up the onset of labor. This happens because substances are released during sex that help speed up contractions and cervical dilation. If you can, keep being intimate until the very last minute!
External factors
The phone won’t stop ringing and messages keep coming in, with everyone wanting to know if the baby has arrived yet! This kind of thing disrupts the mom’s and her close family’s peace, who already have their own anxiety to handle—plus everyone else’s. If you can, avoid and protect yourself from these questions! All you need now, at 40 weeks, is to stay calm and peaceful to ensure a smooth delivery and enjoy your baby’s arrival.
