Votre bébé cette semaine

Your baby is about the size of a head of cauliflower, measuring approximately 14.4 inches and weighing around 2 pounds. This is the last week of the second trimester! The baby now has regular sleep and wake cycles that you may be able to predict based on their pattern of activity and rest. Brain activity increases dramatically this week, with the characteristic brain folds and grooves forming rapidly, increasing the surface area of the brain. The lungs, while still immature, are continuing to develop, and baby practices breathing rhythmically. Baby can now hiccup, and you may feel these as small, rhythmic jolts in your belly — different from kicks.

Ce que vous pouvez ressentir

As the second trimester wraps up, you may feel shortness of breath as your expanding uterus pushes your diaphragm upward, reducing your lung capacity by up to 20%. Leg cramps may intensify, often striking in the middle of the night and jerking you awake. Restless legs syndrome — an irresistible urge to move your legs — affects up to a quarter of pregnant women and typically worsens in the third trimester. Your body is retaining more fluid, which can cause puffiness in your face, hands, and feet. Emotionally, you may start feeling anxious about the approaching third trimester and the reality of labor and delivery getting closer.

Symptômes courants

  • Third trimester begins next week — you may feel both excited and anxious.
  • Leg cramps at night are frequent — they often strike the calf muscles.
  • Shortness of breath increases as the uterus rises higher toward your ribs.

Conseils de la semaine

Start thinking about your birth plan — consider your preferences for pain management, labor positions, who you want in the delivery room, and cord blood banking. Begin packing your hospital bag with essentials: comfortable clothing, toiletries, nursing bra, phone charger, going-home outfit for baby, and car seat installed in the car. For leg cramps, try flexing your foot upward (pulling toes toward your shin) rather than pointing your toes, and ensure you're getting enough magnesium in your diet through leafy greens, nuts, and seeds. If shortness of breath is bothersome, try propping yourself up with extra pillows and practice diaphragmatic breathing. Ask your provider about whether you need the Tdap vaccine, which is typically recommended between weeks 27-36 to pass whooping cough antibodies to baby.

Bien manger

  • Eat calcium-rich foods like cheese, fortified tofu, and kale to support baby's bones.
  • Include slow-release energy foods like sweet potatoes and whole grain toast.
  • Stay well-hydrated but reduce fluids 2 hours before bed to limit night bathroom trips.

Point nutrition

  • Glucose test results may be back — if GDM is diagnosed, a dietitian can help plan meals.
  • Omega-3 (DHA 200–300 mg/day) continues to support baby's brain growth spurt.

Bien-être au quotidien

  • Stretch your calves before bed: stand on a step, lower heels below the edge slowly.
  • Organize baby essentials — car seat, crib, and basic clothing should be ready.
  • Take a prenatal class on breastfeeding if you plan to nurse.

Pour votre partenaire

Research childbirth education classes together and sign up — many options exist from in-person hospital courses to online programs you can do at your own pace. Start assembling a list of questions for the hospital tour, such as visitor policies, labor room amenities, and NICU capabilities. Help her feel less anxious by discussing the birth plan together and making decisions as a team. If she's experiencing leg cramps at night, learn the proper stretch technique so you can help her through them quickly.

Signes à signaler à votre professionnel de santé

  • Blurred vision, upper abdominal pain, and headache together are preeclampsia red flags.
  • Regular contractions before 37 weeks — even painless ones — should be reported.
  • Sudden decrease in fetal movement from your baby's established pattern.
