Pregnancy Week 36: Baby Size & Practice

At 36 weeks

At 36 weeks, your baby is about the size of a bunch of bananas (kele ka guchha), around 47.4 cm from head to heel (NHS), with a WHO median estimated weight of about 2,745 g. Their lungs are probably mature enough to breathe without help, and they can suck and digest breast milk. If your baby has engaged in your pelvis, your bump may drop slightly, with more pressure low down and more trips to the toilet.

Your Baby at 36 Weeks

By now, your baby's lungs are probably mature enough to breathe outside the womb without any help. They will also be able to suck and digest breast milk (NHS).

Fully developed and tightly curled up, your baby will be considered full term in just one week. In a first pregnancy the head has often moved down into the pelvis (engagement); if you have had babies before, it may not engage until you have some contractions (Pregnancy, Birth and Baby).

If your baby is not head down yet, you may be offered external cephalic version (ECV), where your doctor or midwife gently applies a helping hand to your bump to encourage the baby to turn. It is successful around half the time (NHS).

Your Body This Week

Your uterus now reaches all the way up to your ribcage, and in the last month you may feel breathless at times as your baby presses against your diaphragm, which should ease once they move lower. If your baby has engaged, expect more pressure in your lower abdomen and pelvis, more trips to the toilet and more vaginal discharge than usual (Pregnancy, Birth and Baby).

A little wee leaking when you laugh or cough is your body preparing for birth by relaxing the pelvic floor muscles around the bladder. Maternity pads can help, and it is worth stocking up now as you will need some after the birth; keep practising your pelvic floor exercises too (NHS).

When to call your midwife or doctor: Tell your doctor or midwife if your discharge is smelly, green or brown, or if it makes you itchy or sore. Contact them immediately if you are concerned about any change in your baby's movements, as it may be a sign your baby is not well.

Garbh Sanskar This Week

A small daily practice for this stage, from Mamta’s 1:1 sessions. It is tradition and gentle self-care, not medical advice, so keep every check-up and follow your doctor or midwife first.

Mantra: The Garbharakshambika Stotram, a devotional hymn linked to the Thirukarukavur temple near Thanjavur, asks the goddess to protect the devotee and the being in the womb. Reading or softly chanting one verse for a few minutes is enough, and our Garbh Sanskar mantras guide explains where it comes from.
Music: Make a short playlist of calm music or bhajans you love that you could also use in early labour, if your birth setting allows it. Listening now builds a familiar sense of calm for you.
Gentle movement: Mamta often teaches a seated butterfly posture (baddha konasana) at this stage: sit on a folded blanket, bring the soles of your feet together and let your knees fall only as far as feels comfortable, breathing easily, only with your doctor's or midwife's clearance. Never hold your breath, and when you rest, lie on your side rather than flat on your back.
Food: Traditionally, week 36 opens Charaka's ninth month, whose guidance is a therapy for qualified practitioners rather than a food, and nothing to try at home. Simple, warm vegetarian meals such as dal and rice can carry on as part of a balanced diet, alongside the iron, calcium and folic acid your doctor recommends.
Garbh samvad (a line to say to your baby): Soon I will hold you in my arms. Until then, I am holding you close inside.

Check-ups Around This Week, Wherever You Live

From around 36 weeks, check-ups look at your blood pressure, urine and the size of your bump, and many countries add a check of your baby's position or a group B strep test.

Where you live	What is usually offered
India	Government guidance places the fourth of the minimum four antenatal visits between 36 weeks and term. FOGSI's window for the single Tdap dose runs from 27 to 36 weeks, so ask your doctor now if you have not had it.
UK	The NHS offers an appointment at 36 weeks, when your baby's position is checked, with further appointments around 38, 40 and 41 weeks. If your baby is not head down, you may be offered ECV.
USA	Visits have traditionally become weekly from 36 weeks, and ACOG advises a group B strep swab between 36+0 and 37+6 weeks. The CDC's seasonal RSV vaccine window runs from 32 to 36 weeks, so during RSV season this is the last week to have it.
Australia	Pregnancy, Birth and Baby lists the group B strep swab at 35 to 37 weeks and says you may be offered it this week, and the RSV vaccine window closes at 36 weeks. Ask your doctor or midwife how GBS is tested and managed where you are booked.

Schedules change and differ between hospitals, so your own care team’s plan always comes first.

Questions About Week 36

What happens if my baby is breech at 36 weeks?

You may be offered external cephalic version (ECV), where your doctor or midwife gently applies a helping hand to your bump to encourage your baby to turn. The NHS says it is successful around half the time.

Are my baby's lungs ready at 36 weeks?

The NHS says your baby's lungs are probably mature enough to breathe outside the womb without any help by now. Your baby will also be able to suck and digest breast milk, and will be considered full term in one more week.

What is the group B strep test offered around 36 weeks?

Group B strep is a common bacterium that many people carry without symptoms, but there is a small chance it causes a severe infection in a newborn. Women who carry it are typically recommended antibiotics during labour, so ask your doctor or midwife how GBS is tested and managed by your care provider.
