Baby Week 3: Your baby is 3 weeks of age. At this point, he/she can see and track objects from 20 to 35 cm, which is exactly the distance to the eye when feeding the baby. In fact, babies of this age tend to be interested in human faces rather than other objects. You can look directly at the baby while feeding, encourage them to practice eye-focus, then slowly turn their head to the other side to see whether your baby’s eyes are still watching you. Both of these actions help to train your baby’s muscles and eye tracking. Through eye communication, you can also increase your baby’s focus and emotion. 3-week old babies can move their hands and feet flexibly.

As a mother, it is important to understand the signs, symptoms and precautions of Sudden Infant Death Syndrome (SIDS). Sudden infant death is a high-risk group for infants under 1 year of age, which they die suddenly while sleeping. The good news is that although this is the main cause of death among infants aged 1 month to 1 year old, it is still rare. There is no special cause of sudden infant death. As long as you can prevent the following risk factors, you can protect your baby.

Parents or Caregivers

  • Lay down and sleep.
  • Premature birth
  • Underweight at birth
  • Sleeping on a soft surface.
  • The sleeping environment is too hot.

To avoid sudden infant death, the following should be kept in mind:

  • Let the baby sleep when they’re sleepy.
    Research points out that sleeping can reduce the probability of Sudden Infant Death by 50%.
  • Remove pillows, soft toys, or bassinet from the bed before bedtime, as these items may accidentally cover your baby’s mouth and nose and cause suffocation.
  • The baby’s head must be cleared out of any items such as pillow, soft toys or blanket and the room temperature should be set at around 24°C.
  • Do not overdress your baby before bedtime.
  • Some experts suggest that parents can sleep in the same bed as newborns in the first few months, and that soft beds provide a sense of security. Another group of experts believes that sleeping together allows parents to detect and react faster to abnormal breathing or activity. If you decide to sleep with your baby, make sure your mattress is secure.
  • Do not smoke around your baby and stay away from smokers.
  • Giving a baby pacifier while sleeping may reduce the chance of sudden death, but this claim requires more research.

Instead, try to find out the cause of crying, and then fix it. Infant colic may be the cause if baby cries for more than 3 hours a day for more than 3 consecutive weeks. Healthy and well-fed babies can cry madly if they suffer from colic.

If your baby is uncomfortable, it will clench his fist, kick and fart. Infant colic may occur  any time, but usually in the evening. The good news is that infant colic usually does not last long, 90% of the infants improves after 4 months. If you find any abnormalities or have any questions, consult a physician who will provide the best care for your baby.
