Motherhood


You are in the final stretch of the first trimester! As you move through week 11, your baby continues to grow rapidly, and your body keeps adapting to hormonal changes.

It measures between 4 and 6 cm long (about the size of a fig or a small lemon). It weighs around 7 to 10 grams.
Main Changes in the Baby:
Folic acid: Essential for the development of the baby’s nervous system.
Spinach, broccoli, avocado, lentils, asparagus.
Iron: Prevents anemia and helps produce red blood cells.
Lean meats, spinach, legumes, quinoa, egg.
Calcium: Important for the development of the baby’s bones and teeth.
Milk, yogurt, pasteurized cheese, almonds, chia seeds.
Proteins: Fundamental for cell growth.
Chicken, fish (low in mercury), eggs, tofu, beans.
Omega-3: Supports the baby’s brain development.
Fish (such as salmon or sardines), walnuts, flax and chia seeds.
Fiber: Prevents constipation, which is very common at this stage.
Fresh fruit, oats, legumes, whole-grain bread.
Hydration: It is key to preventing dizziness and cramps and improving circulation.
Drink 2–3 liters of water per day. You can also include caffeine-free herbal teas or water with natural fruit.

Foods to Avoid
Raw meats and fish (sushi, ceviche, uncooked deli meats).
Unpasteurized dairy (may contain dangerous bacteria).
Fish high in mercury (tuna, swordfish, shark).

Recommended Exercises
Daily walks (20–30 minutes a day).

Important:
Reduces nausea and fatigue:
Exercise improves blood circulation and can help you feel more energized.
Prevents constipation: It helps regulate bowel movements, reducing bloating and digestive discomfort.
Improves mood: It releases endorphins, which reduces stress, anxiety, and mood swings.
Controls weight gain: Helps maintain a healthy weight without affecting the baby’s development.
Strengthens muscles and joints: Reduces back pain and pressure on the knees and ankles.
Prevents swelling and fluid retention: Improves circulation and reduces the feeling of heavy legs.
Improves sleep quality: Helps you relax and rest better at night.
Benefits for the Baby
Better oxygenation: Promotes blood flow to the placenta, supporting the baby’s development.

Exposure to toxic substances
Do not smoke or be around cigarette smoke.
