Your Baby This Week

About the size of a coconut

Length: ~40cm, 1.3 kg

Quick Answer

At 30 weeks, your baby weighs about 1.3 kg and is approximately 40cm long — the size of a coconut. The big milestone this week: body fat including brown fat is accumulating, which will help with temperature regulation after birth. The brain is maturing rapidly, developing the folds that allow complex thinking. You’re 10 weeks away from your due date — the finish line is in sight. Ab har hafta count karta hai — baby aur aap dono delivery ke liye tayyar ho rahe hain.

Baby Development at Week 30

Your baby is getting ready for life outside:

  • Body fat is accumulating, including brown fat that will help regulate temperature — though full thermoregulation won’t be mature until closer to term
  • Brain maturing rapidly — the smooth brain surface is developing deep grooves and folds, dramatically increasing the brain’s processing capacity. This is one of the biggest developmental leaps of the third trimester
  • Bone marrow is producing red blood cells — taking over from the liver and spleen, which handled this earlier
  • Lanugo (fine body hair) is disappearing — being replaced by actual body fat for warmth
  • Eyes are open during wake periods and baby can detect light and dark — but true focusing develops after birth
  • Strong grip — baby can grasp a finger firmly
  • Practice breathing — chest rises and falls as baby breathes amniotic fluid, training the respiratory muscles

Most babies are head-down by now. If yours is breech, there’s still time — many turn on their own by 34-36 weeks.

Your Body at Week 30

Ten weeks to go. You’re bigger, slower, and more uncomfortable. This is completely normal.

Common Symptoms

SymptomWhat’s HappeningWhat Helps
FatigueThird trimester fatigue is real. Extra weight, poor sleep, increased metabolic demandsRest when you can. Don’t push through exhaustion
HeartburnMay be at its worst. Baby is pushing everything upwardSleep propped up, small meals, avoid eating 2 hours before bed
Braxton HicksMore frequent and sometimes strongerHydrate, change position. If regular/painful/more than 4-6 per hour, call doctor
Shortness of breathMaximum uterine expansion pushing diaphragmNormal. Sit upright, sleep propped. Improves when baby drops (engagement)
Pelvic pain / pressureBaby’s weight pressing down, joints loosening for deliveryPelvic support belt, avoid lifting, rest with hips elevated
HemorrhoidsConstipation + pressure on pelvic veinsFiber, fluids, sitz bath, don’t strain. Tell doctor if bleeding
Difficulty sleepingCombination of everything — size, pain, cramps, urination, anxietyPregnancy pillow, left side sleeping, warm milk before bed, relaxation

Your Body is Preparing for Delivery

Even though you have 10 weeks left, your body is already gearing up:

  • Cervix may start softening — though dilation won’t happen until much later
  • Pelvis joints loosening — relaxin hormone is at work, making room for delivery
  • Colostrum may leak — your breasts are ready to produce the first milk

Tests & Screenings Due

Routine Third Trimester Checks (Every 2 Weeks)

  • Blood pressure — critical for preeclampsia monitoring
  • Urine protein and sugar
  • Fundal height (should be approximately 30 cm now)
  • Fetal heart rate
  • Weight

Growth Scan

If not done recently, your doctor may order an ultrasound to check:

  • Baby’s estimated weight and growth
  • Amniotic fluid index (AFI)
  • Placenta position — if low-lying (placenta previa) was noted earlier, this is rechecked
  • Baby’s position (cephalic/breech)

Hemoglobin Check

If due for a recheck — Hb should be >= 11 g/dL. Third trimester anemia is common and needs to be corrected before delivery (you’ll lose blood during delivery).

If You Have GDM

  • Frequent blood sugar monitoring
  • Growth scans to check baby’s size (macrosomia risk)
  • Discussion about delivery timing

Nutrition This Week

Baby’s brain is developing its most complex structures. Iron stores are being built. Your nutrition in these final weeks directly impacts baby’s health at birth and beyond.

What to Prioritize

  • Iron — baby is building iron stores for the first 6 months of life. Take supplements consistently. Palak, beetroot, jaggery, pomegranate, ragi
  • Calcium: 1000 mg/day — bones are hardening. Doodh, dahi, paneer, ragi, til
  • Protein: 78g/day — baby gaining 200-250g per week now. Dal, paneer, eggs, chicken, chana
  • DHA/Omega-3 — brain fold development needs it. Fish, walnuts, flaxseeds
  • Complex carbs for energy — you’re burning through energy faster. Roti, daliya, oats, brown rice
  • Small, frequent meals — 5-6 per day. Helps everything — heartburn, blood sugar, energy

What to Avoid

  • Very salty foods — blood pressure management is critical now
  • Sugary foods and drinks — unnecessary calories, blood sugar spikes
  • Heavy, oily meals — worsen heartburn and reflux
  • Caffeine — under 200 mg/day
  • Skipping meals — blood sugar drops cause dizziness

When to Call Your Doctor

Red flags at 30 weeks:

  • Reduced fetal movements — fewer than 10 in 2 hours after two attempts. Don’t wait, don’t “try again tomorrow”
  • Vaginal bleeding — any amount at this stage needs evaluation
  • Fluid leaking from vagina — PPROM. Go to hospital
  • Regular contractions before 37 weeks — especially if getting stronger and closer together
  • Severe headache, visual disturbances, sudden face/hand swelling — preeclampsia (8-10% in India)
  • Severe upper abdominal pain — especially right side
  • Sudden excessive weight gain — more than 1 kg in a week
  • Severe, persistent itching — especially palms and soles (obstetric cholestasis)
  • High fever — infection risk needs prompt treatment

What’s Coming Up

  • Weeks 31-32: Baby gains weight rapidly. Brain continues its growth spurt. Most babies settle into head-down position
  • Weeks 33-34: Lungs approaching maturity. Baby’s immune system strengthening
  • Week 36: Visits become weekly. Full-term is 37 weeks — you’re close

Aapke Sawaal (Common Questions)

30 weeks mein baby ka weight kitna hona chahiye?

30 weeks mein roughly 1.3 kg normal hai, lekin har baby alag hota hai. Doctor ultrasound pe growth check karte hain aur expected range se compare karte hain. Agar baby chhota ya bada lag raha hai toh doctor accordingly guide karenge — ghabrayein nahi, monitoring zaroori hai.

Kya ab bhi exercise kar sakti hoon?

Haan, lekin intensity kam karein. Walking sabse safe hai — 20-30 minutes daily. Prenatal yoga bhi acha hai. High-impact exercise, heavy lifting, aur pet ke bal letke kuch bhi avoid karein. Agar exercise karte waqt breathlessness bahut zyada ho, dizziness ho, ya contractions feel ho toh turant band karein.

Delivery ke liye kaise prepare karoon ab se?

Teen cheezein ab se karein: (1) Hospital bag pack karna shuru karein — documents, kapde, baby essentials. (2) Birth plan discuss karein doctor se — normal delivery ya cesarean, pain management (epidural available hai ya nahi), kaun saath hoga delivery mein. (3) Pediatrician finalize karein — delivery ke baad baby ka checkup hota hai. 36 weeks tak sab ready hona chahiye.

Week 30 Checklist

  • Continue daily kick counting — 10 movements in 2 hours, same time each day
  • Keep up prenatal visits every 2 weeks
  • Iron and calcium supplements — don't skip even one day
  • Finalize your hospital bag — should be mostly ready by 36 weeks
  • Discuss birth plan with your doctor — delivery preferences, pain management, who'll be in the room
  • Register for a birthing/labor preparation class if available
  • If baby is breech, ask your doctor about exercises or techniques to encourage turning
