1. Baby's Development at 3 Weeks:

At 3 weeks old, your baby's vision is improving, and they can now track objects from a distance of 20-35 cm. This distance is significant, as it matches the distance between your baby' eyes and yours during breastfeeding. Infants at this age show more interest in faces than objects.

You can encourage their concentration by making eye contact with them while they feed. Moving your head slowly from side to side and observing if their eyes follow you will help exercise their eye muscles and tracking skills. Furthermore, eye contact aids in strengthening the bond between you and your baby.

Physically, your baby can flexibly move both their arms and legs at this stage.

2. How to Support Your 3-Week-Old Baby:

Since crying is their primary means of communication, engage with your baby through your voice and skin-to-skin contact. Your baby can now recognize your voice and distinguish it in a crowd.

Cuddling, caressing, kissing, massaging, and holding your baby will excite them, and they may even respond with sounds like "Ah! Ah!" when hearing your voice or seeing your face. Despite the presence of others, your baby can still recognize you.

3. Health and Safety:

3.1. What to Discuss with Your Doctor:

If your baby is developing normally, you may not need to visit the doctor, but it is essential to:
  • Monitor your baby's urine and stools for any signs of health problems.
  • Administer vitamin K to enhance blood clotting.

3.2. Awareness of Sudden Infant Death Syndrome (SIDS):

Sudden Infant Death Syndrome (SIDS) is a condition that can affect babies under 1 year old. It occurs when an infant dies suddenly during sleep without any prior warning or sign. Although SIDS is a leading cause of death among infants aged 1 month to 1 year, the incidence is relatively low.

While the exact cause is unknown, certain risk factors may increase the likelihood of SIDS, such as parents or caregivers smoking, putting the baby to sleep face down on a soft surface, premature birth, low birth weight, and extreme temperatures during sleep.

To reduce the risk of SIDS:

  • Always place your baby on their back to sleep and ensure the sleep environment is free from pillows, soft toys, and potential suffocation hazards.
  • Avoid overdressing your baby before bedtime and maintain a cool room temperature of around 24 degrees Celsius.
  • Keep your baby away from smoke and avoid smoking around them.
  • Some experts suggest using a pacifier during sleep to reduce SIDS risk, but more research is needed to confirm this.

4. Mother's Concerns:

During the first few weeks, you may feel overwhelmed due to your baby's frequent crying. Remember, crying is their only means of communication at this stage. Don't despair or stress; instead, try to understand their needs and find solutions.

If your baby cries intensely for extended periods, they might have fussy infant syndrome, characterized by uncontrollable crying. This condition is temporary, and most babies outgrow it within three to four months.

If you have any concerns about your baby's behavior or development, don't hesitate to consult your doctor for guidance and support.

At 3 weeks old, your baby is developing their vision and motor skills. Providing love, attention, and appropriate care will strengthen the bond between you and your little one.

Remember to stay attentive to your baby's needs, and if any worries arise, seek advice from your healthcare professional. This phase of development is a precious time for both you and your baby.
