  • Breastfeeding

If you opt for breast milk you may still be deciding between your preferred feeding techniques. You may use expressed breast milk or you can feed directly from your breast or you can even opt for a mixture of breast milk and formula. Your baby may be sleeping all the time and maybe uninterested in eating for the first few days after being born. But you should feed your newborn around 8 to 12 times a day for the first few weeks.

Feed your baby every 2 to 3 hours and on-demand. Within the first week, you will understand when your baby gets hungry so that you can start feeding before your baby starts crying. In case your baby continues to sleep you should wake them up for feeding.

If you face any problem breastfeeding you can call your lactation consultant or doctor so that your supply is established properly. Try to feed your baby from both the breasts so that it helps your supply. If you face problems such as engorgement, sore nipple, excruciating pain, and/or red spots on your breast, you should go see a doctor. 

  • Burping

After every feeding session, you need to burp your baby so that your baby doesn’t form any gas. If you burp your baby during feeding, your baby may spit out a lot. Whenever your baby seems to be uncomfortable or get fussy, you should burp then. 

In the first week, you will understand which position helps to burp your baby. Generally laying your baby against your shoulder or sitting your baby up in an upright position will help to burp your baby.

  • Sleeping 

In the first week, your baby will be sleeping most of the time. The first week may not be the time to start sleep training. Remember that there should be e no bed-sharing but the mother should share the room with the baby’s cradle or crib for at least the first six months. 

Remember to put your baby on its back when they go to sleep. Your baby’s crib should not have any object in it including pillows, toys, or bumpers. You may use swaddling to get your own you want to sleep. 

  • Diaper duties 

For the first few weeks, your newborn will be passing out meconium which looks dark and sticky. Diaper changing for the first few days will be challenging. By the end of the first week, your baby will require frequent diaper changes. 

The Colour of your baby’s stool may vary if you are exclusively breastfeeding. During the first week, the color of your newborn’s stool will transition from tar-like dark meconium to greenish or yellow transitional tools and then finally to regular yellow stool.

  • Umbilical cord stump care

It generally takes around 5 weeks for the umbilical cord stump to fall off. Use some clean cotton balls and applying rubbing alcohol on the stump once a day so that it doesn’t get infected.  Keeping the stump dry will help it to heal faster. 

Giving a complete sponge is not suggested unless you see that the cord has fallen off. If the umbilical cord stump starts to bleed or ooze, take your baby to your pediatrician immediately. 

When to become concerned?

1-week newborns tend to be sleepy almost all the time however if your baby doesn’t wake up after 3 hours for feeding or if it continues to remain lethargic, you should consult your doctor. 1-week old newborns are often susceptible to jaundice. If your baby’s skin or eye color starts to get yellow during the first week you should call your doctor. 

A good way to check for jaundice is to check the baby’s face under sunlight for a yellowish tone. In colored babies, the yellowish tone becomes apparent in the palms and soles. If your baby is not having the recommended number of wet diapers every day, you need to seek medical intervention.


Generally, newborns are given the Hepatitis B vaccine, vitamin K injection, and other screening tests right after their born in the hospital. However, if your baby didn’t receive the vaccines and the injections in the hospital then by the end of the first week you should have a doctor’s appointment.


Your whole life will be turned upside down after your newborn arrives. The first week will go by in a blink. Your baby will be sleeping most of the time during this week and this will give the tired mother to catch some shut-eye whenever possible.

The new mother should take lots of rest during this time to facilitate recovery. The number of changes may seem overwhelming but don’t worry you will get the hang of things soon.
