2 Week Old Baby’s Development Guide For Parents


Parenthood is a wonderful experience for any mother. However, it may get confusing at times, especially if you are dealing with your first child. By week 2, you have probably adjusted to a pattern that goes something like this: feed, change the diapers, rock, and repeat. And whenever you find some free time, you are probably still focusing your eyes on your newborn, admiring the beauty of parenthood.

But, there is still a lot to learn and you are going to notice something different about your baby every day. You will be learning about its different types of cries as well as slight signs of hunger. In case it ever gets a bit tough, it is a great idea to know what exactly your 2-week old baby has in store for you.

What You Must Know

  • You should incorporate a sleep routine
  • Consult your doctor in case you are experiencing bleeding while nursing or significant pain
  • It will become apparent if your baby is having any troubles with nursing during this period
  • Just go with the flow when it comes to feeding
  • Do not forget to take care of yourself as well

Baby development 2 weeks old will certainly be an exciting period. This is the right time to get to know each other and perhaps start exploring the surroundings (not too much though because you are still recovering). Both you and your newborn will be feeling more alert and awake after birth during this period.

Going into week 2 may be a good time to introduce a sleep routine, but you should not stress about it if it does not go too well. Your little bundle’s circadian rhythm and brain functions will create a schedule in the following weeks.

During this week, you should follow your baby’s demands when it comes to feeding. It will experience a significant growth spurt this week so you may feel like you constantly have to feed it. You should monitor your baby to make sure it is experiencing at least three yellowish stools a day. Besides, your baby should be wetting at least six diapers daily during this phase.

It is important to remember to take care of yourself as well by taking note of how you are feeling. 2 weeks after birth is a transition period because your hormones will change. Make sure you are vocal about your mental health, speaking with your care provider or your partner.

Your Baby is Growing

Your baby will be back to its birth weight, no matter if it lost a bit in the first week of its life. Some babies will also weigh a bit more than they did after birth during this period.

Your 2-week old baby will reach some significant milestones, beginning with the first growth spurt happening around day seven. You might notice your newborn is behaving differently during this period of its development. For example, it may eat and nap more, and be fussier than usual. No need for concern since this is a normal part of the development.

You may also notice your baby is growing right in front of you. It will continue to do so, gaining 2/3 of an ounce (20-30 grams) a week, resulting in 1.5-2 inches (4.5-5 centimeters) by the end of its first month.

Any misshapenness or swelling of your baby’s head will be gone by this time so it may appear smaller than usual. This is no reason for concern since it will continue to grow without any problems.

Milestones in the Development


What you will notice right away is that your baby is more alert than the previous week. Also, it will be able to stay awake for longer. Because of all these changes, your baby’s eyes may appear crossed or like they are rolling back in its head. Do not be alarmed since this is a completely normal part of baby development 2 weeks old.

In case your infant has experienced mild bruising or scratches on the eyelids during the delivery, any residual wounds should disappear by this time. The force from the delivery and contractions may cause some infants’ blood vessels to break. However, any red spots in their eyes should resolve during this week so there is no need to worry.

Your baby may suddenly get birthmarks, such as strawberry hemangioma, during baby development two weeks old. Also, any birthmarks your child has may appear darker as your baby grows and develops. Make an appointment with your baby’s doctor in case you see unusual birthmarks. It is important to get the right treatment especially if you notice they are close to your baby’s eyes or mouth.


Your 2-week old baby will be able to:

  • Hear louder noises
  • Cry whenever it is hungry, uncomfortable, or fussy
  • Briefly lift its head up
  • See you at a short distance. Infants of this age have the range of vision which is equivalent to the distance between the mother and the baby when nursing
  • Have a startle reflex

When You Should be Concerned

There are potential issues that your baby may experience at this time. If there are any issues with hearing, the newborn hearing screen will typically be able to determine the problem. You should consult a pediatrician if your baby appears to be crying inconsolably, if it has trouble waking up, or if it does not respond to loud noises.

Everyday Life with a 2 Week Old Baby

Your baby should be sleeping up to 18 hours a day during this stage even though it will be more alert than it was during the first week. It might be a good idea to start using a baby carrier to keep your child close to you since you will be getting stronger.

A 2-week old infant will be comforted by staying close to you or your partner. Skin-to-skin contact has many benefits for babies. For example, it can promote weight gain, regulate body temperature, as well as increase breast milk supply. Your newborn will love your touch and will bond with you during feeding sessions.

Basics of Baby Care


Bath Time

You can start bathing your baby once its umbilical cord falls off. What an exciting time in baby development 2 weeks old. Simply get a baby bathtub to check whether your little bundle enjoys the water. If not, do not be alarmed because it will certainly start to enjoy it with time.

Creating a bath time routine might help your newborn adjust to the water. For example, creating a nighttime routine can make your baby realize that it should soon fall asleep. The most suitable way to get your infant to sleep may be feeding during this stage even though experts do not recommend it.

Instead, you could try giving your baby a massage or a bath before laying it down to sleep. However, you should remember that newborns do not need a bath daily. During this stage, your little one will be satisfied with having a bath once a week or every few days.

Umbilical Cord

The umbilical cord should fall off during the baby development 2 weeks old. However, if that is not the case, you should consult your doctor to learn more about the methods to help dry it out. You should give your baby a lot of ‘’airing out’’ time as well as avoid getting it wet. The skin around the cord should not be too moist all the time. Also, never try to loosen the cord by pulling it. It is enough to simply be patient because the cord will come off when the timing is right.

When the umbilical cord finally comes off, you may be unsure about what to do next. Some parents keep their baby’s cords, while others throw it away. What you decide to do with it is your own choice.


At two weeks old, your baby should be done with meconium, which is black, tarry stool that is normal during the first few days of its life. After this stage, your baby should be experiencing three or more bowel movements every day. The stool should be loose and may look yellow as well as ‘’seedy’’. Also, your 2-week old baby should wet six or more diapers every day. You could use disposable diapers with indicator patterns or lines to make sure your newborn has done the job.


Your baby should be waking up to feed every two to three hours during this time. The feeding sessions should last from 15 minutes to almost an hour. Keep in mind that the sessions start from the time your baby starts feeding. For example, if you start feeding your infant at 3 a.m. and it stops eating at 4 a.m., it may be going to get hungry again around 5 a.m.!

The good news is that breastfeeding will become less frequent as your baby grows. It may feel like a full-time job at the moment but you will certainly have more time for yourself in the following period. There is a big growth spurt during week 2, so your little one needs more milk to properly develop. In case you feed your baby formula or use formula together with breast milk, your baby may want to sleep for longer. However, it will still need to be fed every four to five hours.

It is crucial to learn to recognize your newborn’s hunger cues because proper nourishment means proper development, especially during this early phase. Your baby may be too stressed, frustrated, or even tired to latch on if you wait until it is crying. Instead, pay attention to the following signs your baby is hungry. Your baby might be:

  • Moving its legs and arms all around
  • Awake or just waking up
  • Trying to put its fist or fingers into its mouth
  • Sucking on its tongue or lips
  • Moving its head from side to side
  • Turning towards your breast while you hold it
  • Sighing, cooing, or whimpering
  • Making different faces
  • Fussing, wiggling around, fidgeting, squirming, or restless

Your little one may not have a strict schedule when it comes to eating. You may notice this by following these hunger cues. Instead, your baby may want to cluster or bunch feed. It means it will want to eat a bunch of times during a short period and then fall asleep. This kind of feeding pattern is normal for this period of development, so do not be alarmed. Offer your baby food when it seems hungry, even though it may appear frequent.


Your 2-week old baby is going to sleep a lot during this stage, up to 18 hours a day! If it is not experiencing jaundice and is having at least three dirty and six wet diapers a day, then it is safe to let it sleep five hours or longer during one sleeping session.

You are most likely feeling much stronger after birth during week 2 so you may have the desire to move around more. According to the American Academy of Pediatrics, the safest place for your baby is its bassinet or crib. So, in case you are on the go, you should not let your baby stay asleep or fall asleep in:

  • Swings
  • Car seats
  • Baby seats, such as bouncy seats
  • Your or your partner’s arms

Safety and Health

If your newborn has already had its first check-up with its pediatrician, you might not need to arrange another one before it becomes one month old. But, some pediatricians may have different guidelines or may want to see your baby if it is experiencing any issues.

If your baby has received the Hepatitis B vaccine at birth, it should not need new vaccinations at this stage. Your pediatrician will be monitoring your little one’s eating and growing since this is the focus of week 2.

To stay safe and avoid complications, you should follow these tips:

  • Do not leave your child alone on a changing table, bed, couch, or any other elevated surface. It is true babies cannot move very far but they can scoot or slip to an edge so you should never leave them unsupervised.
  • Set rules when it comes to visitors or taking your baby out. Your baby’s immune system has not fully developed yet so you should limit its exposure to germs. Do not be afraid to ask potential visitors to stay away until your baby becomes stronger.
  • Beware of the symptoms of illness. Immediately contact a doctor if your baby is experiencing a decreased appetite, irritability, vomiting, lethargy, or a temperature of 100.4 degrees Fahrenheit.
  • Get vaccinated. It may be a good idea to get the whooping cough vaccination to protect your child even more.

Around this time, the excitement of parenting can start to decrease so you may feel fatigued, stress, or sleep deprivation. That is why it may be a good idea to see your OB/GYN. At the end of this week, you may be experiencing ‘’baby blues’’, which is normal emotional instability after birth, different from postpartum depression. You should be aware of the potential issues you might experience during this period:

  • Issues with breastfeeding: Incorrect baby’s latch may cause you bleeding or cracked nipples, pain, or even your baby’s reluctance to nurse. Speak to your doctor if you are experiencing such issues or look for a lactation consultant.
  • Mastitis: This is a complication that may occur when breastfeeding. It is more likely to happen if your infant is not fully emptying your breasts or you have an over-supply of milk. A painful infection can develop if milk gets clogged in the milk ducts. In case you notice a red spot in your breast followed by a fever and fatigue, contact your doctor.
  • Complications after birth: It is a good idea to look for any possible complications since your body continues to heal. Check your incision for any swelling, redness, tenderness, or drainage in case you’ve had a C-section. On the other hand, look for foul-smelling discharge, a sudden increase in bleeding increased pain in the pelvic area, or large clots in case you’ve had a vaginal delivery. You should generally be feeling better during week two, so seek medical attention if that is not the case.
