Votre bébé cette semaine
Your baby is about the size of a carrot, measuring around 10.5 inches long and weighing approximately 12.7 ounces. Movements are becoming stronger and more coordinated — you may feel distinct kicks, rolls, and somersaults throughout the day. The baby's digestive system is maturing as they swallow amniotic fluid and absorb small amounts of sugar from it. Taste buds are fully developed now, and studies suggest babies can taste what mom eats through the amniotic fluid. Eyebrows and eyelids are fully formed, though the eyes remain fused shut.
Ce que vous pouvez ressentir
Stretch marks may begin appearing on your belly, breasts, hips, or thighs as your skin stretches rapidly to accommodate your growing uterus. You might notice varicose veins developing in your legs due to increased blood volume and pressure from the uterus on your pelvic veins. Heartburn and indigestion are becoming more frequent as your expanding uterus pushes against your stomach. Your appetite is likely increasing significantly — your body needs about 300-350 extra calories per day during the second trimester. Some women also experience mild swelling in the ankles and feet, especially toward the end of the day.
Symptômes courants
- Baby's movements follow a pattern — you may notice active and quiet periods.
- Heartburn worsens as the uterus pushes stomach acid up into the esophagus.
- Stretch marks may become more prominent on your belly, hips, and breasts.
Conseils de la semaine
Moisturize your belly, hips, breasts, and thighs regularly with cocoa butter or vitamin E-rich creams to help skin elasticity and reduce itchiness from stretching. Stay active with moderate exercise like walking, swimming, or prenatal yoga — aim for at least 30 minutes most days, as this helps with circulation and can reduce swelling. Include iron-rich foods like lean red meat, spinach, and lentils in your diet, as your blood volume continues to increase and iron needs are higher. Wear compression stockings if varicose veins are bothering you, and avoid sitting or standing in one position for extended periods. Continue your prenatal vitamins and ensure you're getting enough calcium (about 1,000 mg daily).
Bien manger
- Eat smaller, more frequent meals (5–6 times a day) to minimize heartburn.
- Avoid spicy, acidic, and fried foods that trigger reflux.
- Include oatmeal and whole grain bread — complex carbs help buffer stomach acid.
Point nutrition
- If heartburn limits your diet, a prenatal vitamin ensures you still get key nutrients.
- Probiotics (from food or supplements) can improve digestion and reduce bloating.
Bien-être au quotidien
- Sleep propped up on pillows or elevate the head of your bed 6 inches for reflux.
- Aqua aerobics is an excellent exercise — water supports your weight and reduces swelling.
- Begin researching pediatricians so you have one chosen before birth.
Pour votre partenaire
Help apply lotion or oil to hard-to-reach areas like her lower back and sides — this can also be a wonderful bonding moment. Start discussing nursery plans and baby names if you haven't already — she may appreciate having these conversations as the pregnancy becomes more real. Consider planning a babymoon trip while she's still comfortable enough to travel. Attend prenatal appointments when possible to stay involved and informed about the baby's development.
Signes à signaler à votre professionnel de santé
- Chest pain or difficulty breathing beyond mild shortness of breath needs evaluation.
