Newborn Stage

Topic1 Newborn Stage

Baby's newborn skin is very delicate, and is easily prone to rashes.

To help reduce the incidence of rashes it is imperative to keep your baby dry between changes. To achieve this be sure to use diapers that absorb quickly and lock the moisture away, and change as often as necessary.

Development Approximate size Weight: Birth ~ 5kg

Body overall

When baby is a newborn,his torso and limbs are still slender,and he looks a bit different from the image of a round, plump baby.


Baby's head is a bit misshapen,and it may have a bump on it. On the top, there's a gap (called the anterior fontanel) where the bones don't meet, but the head will gradually take on a more normal shape, and the gap will close by age 1 or 2.


Slender and unsteady. Unable to support his heavy head, his neck is wobbly.


The natural shape is like a "W," with both hands lightly clenched and elbows bent. This is the same position as when he was in mom's belly.


Knees are bent, and legs are opened toward the outside. The hip joints are unsteady,so this letter "M" position is the natural shape.

Belly button

The umbilical cord will come off about 1 week after birth.

After that, it will still be moist and damp-feeling until about the 1-month mark.

The top edge of the diaper may rub against it and cause pain or a rash.


Body temperature is slightly high, around 37 degrees C.

Baby cannot regulate his body temperature yet,so you'll need to adjust the room temperature, his clothing, and his bedding accordingly.


Compared to an adult's skin, baby's skin is much thinner and more fragile and delicate. Baby's metabolism is especially active in the newborn stage, and he perspires a lot. There are also a lot of skin secretions. As a result, the oil glands around the head and eyebrows may get clogged, causing a yellow eczema breakout. And a heat rash may appear around the face or the back of the neck, where there are a lot of sweat glands. Baby may scratch himself with his own fingernails and cause a bacterial infection. Also, watch out for a stopped-up nose, as it will make it difficult to nurse or drink formula.

So when it comes to things that touch baby's skin, try to choose soft, gentle textures.

Breastfeeding, formula

With its good balance of necessary nutrients, breast milk is the best meal for baby. But when you can't produce enough breast milk, it's OK to supplement with formula that is patterned after breast milk. At first, baby makes no distinction between day and night. He'll wake up every 2-3 hours and cry and want milk, so give him breast milk or formula whenever he wants it. Even if he can't drink well at first, don't worry, as he will gradually learn to suck and swallow well. Since baby's stomach at this age is small and its entrance doesn't close tightly, he may spit up some of the breast milk or formula he drinks.

So a newborn's bowel movements are runny and frequent.


Even though baby is in bed all day, his metabolism is active. So to wash away things like sweat and sebum (skin oil), give him a bath once a day. In the newborn stage when the immune system is still weak, give him a tub bath using a baby bathtub. Since baby was immersed in amniotic fluid all along in his mom's belly anyway, he'll love taking a bath. Being immersed in warm water even for just a few minutes will warm up baby's body temperature and make him feel good. It also improves blood circulation and provides some good exercise.

So after a bath, baby will usually drink a lot of milk and sleep well.

Clothing changes

Just by drinking milk and crying, etc., baby can get drenched in sweat. As his undergarments soak up all that sweat, you'll need to change them many times throughout the day. So stock up on lots of undergarments. In this stage, his neck and back are unsteady, so in order to be able to change his clothes with him lying down, the best undergarments and clothing are kimono-style garments that tie closed in the front. Because baby's skin is sensitive and delicate, if things like a collar or frills rub against the skin, skin can become red and puffy.

So undergarments and clothes for a newborn are best kept simple.

A baby's day

A newborn baby's day is a recurring cycle of nursing or drinking formula, sleeping, waking up hungry again, drinking again, and sleeping again. It's said that a newborn sleeps from 10 to 20 hours per day. His sleep is light, and he doesn't distinguish between day and night. So every 2-3 hours he will get hungry and wake up. He'll want milk and cry to his mom.

So through all these physical contacts with mom, baby and mom develop a close bond.
