Week by Week

What do you need to know to care for your 3 week old baby?


Development & Behavior

How should my baby be developing?

Your baby is now 3 weeks old. At this time, your baby can see and track objects at a distance within 20-35 cm. This is the distance between your baby’s eyes and you when you breastfeed. In fact, children in this age tend to express interest with faces rather than other objects. You can encourage them to practise focusing by looking straight into the baby when breastfeeding. At the same time, move your head slowly from side to side and see whether his eyes are watching you or not. This helps exercise muscles and eye tracking skills for children. Communicating by eye contact also helps increase the alignment and motherhood. At 3 weeks of age, your baby can move flexibly with both hands and legs.

How to support my baby?

The only way your baby knows to communicate with others is crying while you can contact with them through your voice and your touch. They can now recognize your voice and pick it out among others.

Your baby probably loves to be held, caressed, kissed, stroked, massaged, and carried. They may even make an “ah” sound when they hear your voice or see your face, and they’ll be eager to find you in a crowd.

Health & Safety

What should I discuss with doctor?

Typically, you do not need to take your baby to the doctor if they are developing normally.

However, you should observe your baby for signs of any serious problems. You should:

  • Monitor urine output or number of bowel movements so you can be able to detect your baby’s any health problems;
  • If there are any blood clotting issues, your doctor may suggest injections of vitamin K to enhance blood clotting.

What should I know?

As a mother, it’s important to know the signs of sudden infant death syndrome (SIDS) and how to prevent it. Sudden infant death syndrome refers when the baby dies suddenly during sleep. Infants under 1 years old are more likely at risk for this serious condition. The good news is though this disease is the leading cause of death among babies between 1 month and 1 year, it’s still rare. There are no real cause for the illnessbut you can protect your baby by understanding these risk factors:

  • A parent or caregiver who smokes;
  • Sleeping face down on the mattress;
  • Being born prematurely;
  • Low birth weight;
  • Sleeping on a too-soft surface;
  • Being too hot while sleeping.

To prevent risk of SIDS in infants, you should do the following:

  • Always put your baby to sleep on their Studies have shown that cases of sudden infant death syndrome have dropped 50 percent from having the baby sleep on their back. Even putting your baby to sleep on his side isn’t advisable. Clear the cradle or crib of any pillows, soft toys, and bumpers, which can unexpectedly cover your baby’s mouth and affect their breathing. Keep your baby’s head uncovered. Keep the room cool around 24 degrees Celsius.
  • Don’t overdress your baby at bedtime. Some experts advise sleeping with your newborn in your bed during the early months on soft bedding can bring Others believe that sharing a bed allows parents to respond more quickly to changes in their baby’s breathing or movements. If you do co-sleep, make sure the mattress is firm. Your baby should sleep on his back even in your bed.
  • Never smoke around your baby and keep them away from those who smoke. It’s possible that breastfeeding your baby and giving tem a pacifier during sleep may lower their risk for the disease, but more researches are needed to confirm these links.

My Concerns

What I am concerned about?

In the first weeks of life, you may feel quite depressed because your baby always cries. But crying is their main method of communication with you right now. In stead of despairing or feeling tense, you should try to find out why your baby cries and then  solve it. However, if they are crying for more than three hours a day and this lasts for three weeks, they may have colic. Colic is extended frantic crying in an otherwise healthy and well-fed infant.

Many babies will be unable to be soothed, they can clench their fists and draw up their legs. They also fart. The “colicky” episodes come anytime of the day, often suddenly in the evening hours.

But the good news is that colic does not lasts for a long time. 60% of babies will get rid of this condition within three months, and 90% would be better when they reach four months old.

Ask your doctor if you feel any signs of abnormal or if you have any questions. Your doctor will give way and guide best care for your baby.
