Day 212 baby development and maternal changes

A: Include: preferred mode of delivery (the medical indications for natural/caesarean), whether to have epidural analgesia, whether episiotomy is acceptable, delivery-position preferences, whether to delay cord clamping, rooming-in, and breastfeeding intention. Print a copy to take to the hospital so staff understand your wishes, but with maternal-fetal safety as the priority, adjust per the doctor’s advice.

A: The small scan is generally arranged at weeks 30-32, so at week 31 you’re still in the window — complete it as soon as possible and don’t let it pass week 32. It assesses fetal growth, amniotic-fluid volume, placental position and maturity, fetal position and umbilical blood flow.

A: Colostrum is the thick yellow milk secreted first after birth, rich in antibodies and nutrients, known as "liquid gold". A little colostrum in pregnancy is normal — don’t deliberately squeeze or stimulate it (it may trigger contractions); after birth, let the baby suckle as early as possible.

A: A growing uterus pressing the intestines and progesterone slowing bowel movement make constipation worse. Eat more sorbitol-rich foods such as prunes, pears and kiwi, coarse grains and vegetables for fiber, drink 1.5-2L of water daily, walk after meals, and toilet regularly without squatting long. Iron supplements can worsen constipation — discuss an adjustment with your doctor; in serious cases choose a pregnancy-safe laxative rather than a stimulant laxative.

A: A cumulative gain of about 9.5-13.5kg by week 31 is common. For a standard BMI, the third trimester is about 0.4-0.5kg a week and the whole pregnancy recommends about 11.5-16kg. Watch the overall trend and manage by BMI with a weight-gain calculator.

A: Yes. In the third trimester the baby starts storing large amounts of calcium, iron and other minerals in preparation for birth, so you should keep calcium (1000mg a day) and iron (about 27-29mg a day) ample — food first, supplements per the doctor’s prescription when insufficient.

A: It’s not recommended. Shining a torch on the belly for "light fetal education" has limited evidence and no proven benefit; light through the belly is faint and may disturb the baby’s rest. Talking, reading picture books and listening to soothing music are steadier choices for fetal education.

A: The three measurements at 31 weeks: BPD (biparietal diameter) about 78.5mm, AC (abdominal circumference) about 268.0mm, and FL (femur length) about 57.5mm, reflecting head, abdomen and leg development. If the three are in step, growth is good; a single slight deviation isn’t necessarily abnormal — go by your obstetrician’s overall assessment.

A: Most babies have obvious active periods. Since week 28 you should count fetal movements daily: one hour in the morning, afternoon and evening each; ≥10 within 2 hours is normal. If it’s clearly under 10 in 2 hours or down by more than half from usual, seek care immediately.

A: ACOG advises women without complications about 150 minutes of moderate-intensity exercise accumulated weekly (walking, prenatal yoga, swimming), split over 5 days at about 30 minutes a day. In the third trimester focus on walking and stretching; avoid intense exercise and pressure on the abdomen; stop and seek care for pain or bleeding.

A: Yes. The CDC and ACOG recommend the Tdap whooping-cough vaccine at weeks 27-36 to prevent Pertussis in the baby; the inactivated flu vaccine can also be given in flu season. Both are pregnancy-safe vaccines; tell them you’re pregnant before vaccination.

A: If there’s no placenta praevia, bleeding, cervical insufficiency or threatened preterm labour, gentle sex is fine using positions that don’t press on the belly and with gentle movements. The closer to term, the more caution in the third trimester; pause if unwell or the doctor advises against it; seek care for post-sex bleeding, pain or leaking fluid.

A: When a cramp hits, flex the foot and massage the calf; prevention relies on supplementing calcium and magnesium, drinking water and stretching before bed. For swelling, raise your legs, lie on your left side, walk to promote return flow, and moderately limit salt. If swelling suddenly worsens, spreads to the face and hands, or comes with headache or vision changes, check blood pressure to rule out preeclampsia.

A: Avoid raw or undercooked meat, fish and eggs, high-mercury large fish, unpasteurised dairy, alcohol, caffeine over 200mg a day, and excess animal liver. If you have GDM, strictly control refined sugar and sugary drinks as well.

A: Eat smaller meals more often and chew slowly, sit or stand for 30 minutes after meals before lying down, avoid eating in the 2-3 hours before bed, avoid spicy, greasy, overly sweet food and carbonated drinks, and prop up your upper body when sleeping. In serious cases, use a pregnancy-safe antacid under a doctor’s guidance.

A: It comes from a forward centre of gravity and ligament relaxation. Avoid long standing or sitting, wear supportive low-heeled shoes, use a belly-support belt, side-sleep with a pregnancy pillow, do prenatal yoga and pelvic-floor exercise, and apply local warmth. Sharp pain on one side or with bleeding and fever needs care.

A: A growing belly, frequent urination and trouble turning over affect sleep. Use a pregnancy pillow for support, sleep on your left side, soak your feet before bed to relax, reduce evening fluids to cut night urination, and exercise moderately during the day. Avoid screens before bed and caffeinated drinks.

A: It sorts into three: mum’s supplies (maternity pads, nursing bra, toiletries), baby’s supplies (NB nappies, swaddle, going-home outfit), and documents (ID card, social-security card, prenatal records). Prepare it in batches before week 34 and keep the list by the door so you can leave at a moment’s notice.
