Your Baby's Second Week After Birth

The 2-week old baby’s health and development will seem to perhaps spurn in this very week for the first time as they become needier and will get hungrier more often. Perhaps, make sure you are ready beforehand and have a good supply of milk as the little one is completely dependent on you.

Adding on, Baby’s sleep is still pretty erratic at this early stage, so make sure you pace yourself too and when you can. In case you require help, do not shy away and get the helping hands on board. This is the time for work and togetherness for the betterment of both you and the baby. Read on to know what else you can expect from this second week after birth.

Your 2-Week-Old Baby's Development And Physical Growth

Let us now understand what happens with the little one in their second week after birth in terms of their physical development in the second week after birth.

1. Your baby's weight:

  • As opposed to the first week, the little one in their second week will have surpassed or regained their birth weight by 10 – 14 days of life. This is due to the feeding, whether from the breast or the bottle formula feeding. Also if your baby was born at term ( at 9 months ) or before term because usually babies born at term gain weight by 2 weeks and preterm gain weight by the 3rd week.
  • It is ok if the baby may get off to a slow start in breastfeeding as it may take a little longer to put on pounds. However, until the baby’s doctor isn’t worried, you shouldn’t either. All you need to do is to make sure that the baby is well fed every two to three hours, counting from the first feed.

2. Your baby's sleep:

  • The 2-week old babies, until up to 3 or 4 months, will require about 14 to 17 hours of sleep in a 24-hour period. And, they usually wake up for their feed every two to four hours. This is because they are still developing themselves and the body, perhaps, is slowly getting used to the schedule outside the protected and warm belly. Also, do not forget to catch your sleep too along with the baby when possible.

3. Your baby's diet:

  • Newborn babies consume roughly around 16 to 24 ounces of breast milk or formula in a 24 hour period.
  • An easy rule is to feed your baby once every 2 hours typically for 20 minutes and gradually build up the duration.

Your Newborn And 2-Week-Old Baby's Reflexes

The 2-week old baby might seem to not be doing way too much as you’d have expected them to. Their cycle would generally involve eating-sleeping-pooping. However:

  • The two weeks old baby is using their baby brain plenty, cycling between intently watching the surroundings and spending time in the drowsy phase. This phase could be the little one either about to fall asleep or just waking up.
  • Though in the first year, the infant might seem like a helpless newborn, they are making lots of developmental strides, including them being able to focus on a face, in their second week after birth. 
  • Fun fact, you may not be able to decipher between the baby’s true eye color until somewhere between 6 and 9 months, and might also keep changing until as late as their third birthday.

Your Newborn And 2-Week-Old Baby's Health

There are no shots due to appointments at the doctor’s (hurray!), but there are a few things you’ll require to keep in mind regarding the baby’s health.

  • The weight of the baby

As per the American Academy Of Pediatrics, the general healthy weight gain of a newborn in their second week is between 5 pounds 11.5 oz, and 8 pounds, 5.75 oz.

  • The right way to help the baby get their much-needed sleep

It is recommended and observed that the safest place for the little one is to sleep in a baby bassinet or a  crib. Make sure to use a baby flat head pillow to place the baby’s head and keep them flat on their back to sleep, until they are 1 year old.

  • Circumcision care for a baby boy

If the newborn baby boy is circumcised, in order to treat, it would take about 7 to 10 days to heal. Therefore, parents must be very gentle and clean the area when you change the diapers a day with warm water.

  • Your baby being cross-eyed

Your baby may seem to be cross-eyed. This is because the newborns’ are born with some extra skin that folds in the inner corners of their eyes and also because they don’t have full muscle control. But, you need not worry as the newborn will outgrow it as and when they grow and the folds will add to their nose or will disappear.

  • Umbilical cord infection in the 2-week-old baby

This rare umbilical cord infection, also known as omphalitis is a case that would require immediate medical attention. The infection occurs as and when the cord is cut or a few days after birth. Don’t meddle with the cord or try to pull it off, just leave it to fall on its own.

Your Baby's Soft Spots

Have you noticed two hole-like soft spots on the baby’s head, especially in these initial weeks after birth? Know what these are or why they are present in the first place?

It’s shaped like a diamond up to 2 inches across that begins to close when the baby is 6-months-old up until 24 months. These are known as fontanelles and are there for two main reasons.

  • It enables the little one’s head to have space and allows room for the growth of their brain in the first year.
  • Those soft spots are covered with strong membranes that are responsible for safeguarding the brain.

Note – In case the fontanel is depressed, this could indicate dehydration, and a constant bulging would indicate pressure on the brain. In either case, you must make sure to contact the baby’s doctor.
