Healthy and Normal baby weight gain

A healthy weight in a baby during birth comes to newborns. It is about peeing, eating, and pooping; it has nothing to worry about. The average newborn weight of babies is around 7.5 pounds. It may slightly vary depending on the ethnicity/race of the baby. Nearly 8/10 babies are born weighing full-term between 11.5 oz, 5 lb, and 5.75 oz which is Normal Baby Weight Gain.

In case your baby is a newborn, there is nothing to worry about the baby’s size. If she is smaller or bigger, your practitioner will perform some tests or monitor to ensure she is healthy.

On average, the birth weight is 3.5kg or 7.5 lb in babies, although most babies are in the ranges of 2.5kg or 5.5lb and 4.5kg/10 lb. This weight is normal. The boys mostly weigh more than the girls, and usually, the first babies are lighter to their later siblings.

Some weight is lost after birth.

Normal Baby Weight Gain 1

After the discharge from the birthing center or the hospital, your baby will lose around 5 to 10 percent lesser weight, in comparison to that she was weighing at birth. Nothing alarming. 

The loss of weight after birth in a baby is because she loses the fluid. Babies are born with surplus fluid, and it is normal to lose a few ounces. In the initial days of life, the fluid reduces. A healthy newborn baby loses 7 to 10% of its birth weight. However, there is nothing to worry about as the same weight is back in 2 weeks as maximum. A normal baby weight gains within 5 days after the weight loss, and within 14 days, she is back right away.

A normal factor for babies is in losing weight, no matter how and what they are fed. Breastfed babies normally lose weight after birth for the initial 3 days. The weight loss is in the birthweight percentage. The weight loss to the maximum in the initial week is 7 to 10%, and it is normal. 

Most babies lose one-tenth of their weight, and within 2 weeks, they come to original birth weight. The newborn gain weight daily at 20-30 grams and in a month around 4.5kg.

Babies vary in size and shape, the same as the grown-ups. The weight your baby is gaining with every passing month relies on factors such as genetics, the amount she is fed if it is a formula or breast milk. Breastfed babies gain weight in two months but grow less rapidly than their formula-fed babies in the first-year remainder.  You can read Getting Toddler To Gain Weight

Here is a rough guideline to gauge your baby’s on track:

From birth to 1 month: An average newborn gains a day around 2/3 to 1 ounce and grows in length around 1 to 1 1/2 inches in the whole month. Most babies in the initial few days lose some weight but regain the weight in the next few days. Thus, within 7 to 10 days, their original birth weight is back.

From 1 to 4 months: Babies acquire 1 1/2 to 2 pounds, and each month grows 1 to 1 1/2 inches. At this time, your baby looks chubby; as you can see, there is an increase in the activity level. The baby rolls replace developing muscle.

By 6 months: Babies double their birth weight.

By 12 months: Most babies triple their birth weight and grow 9 to 11 inches from the original birth length.

By 24 months, most babies quadrupled in their birth weight and grew from 14 to 16 inches from birth.

With each visit to the pediatrician, your baby’s weight, head circumference, and height are taken into track or record on the growth chart. It is a standard chart to determine the baby’s progress with the same sex and age groups. Parents worry about the measurements of the baby on the low or high end. Though these are normal concerns, your child’s percentile is not more important than the consistent growth that he or she is showing. When your pediatrician is calm about the growth patterns and size, you can also stay calm.

Length and head circumference growth

The distance of the child’s forehead center and the farthest part of the head’s backside is the head circumference. The measurement is done using a tape measure. Some babies are fussy while getting the measure of their head circumference. The measurement helps the doctor in determining the growth of the head circumference.

At birth, the brain is 25% of the adult size, while 35 cm is the head circumference. In the first year, the head circumference has a 1cm/month increase. The growth is rapid in the initial 8 months. The brain receives its postnatal growth by 12 months and is in the adult size to 75%.

The head of the baby grows at a fast rate after birth in the initial 4 months. Brain growth shows a rapid increase. The head circumference at an average at birth is 13.5 in or 34 cms. However, it increases in size to 15in/38 cm by the first month-end.

Apart from measuring the baby’s weight and height during the baby checkup, the pediatrician measures the distance around the baby’s head. This measurement is the head circumference, and it helps to gauge the brain growth of the baby.  

The baby’s skull and her head consequently increase in size so that the growing brain accommodates easily. The soft spots on the head of the baby are known as fontanels. It remains open in the initial 18 months and allows room for expansion—the head of newborn measures around 13 ½ inches. 

You will experience in the baby a rapid head growth in the initial four months. The head circumference by the first-year end will be around 18 inches. In the second year, the baby will add an inch, and the head of the baby is close to the head of the adult size.
