Newborn Baby Weight: What Are The Normal Development Values?

Although your baby`s weight seems normal, he may be even too small or too heavy. What to do? You should contact a doctor, change your diet or do gymnastics? Well, these are all good options.

Newborn Baby Weight

Any child who is younger than 1 month can be considered an infant. Soon after birth, the doctor will make a careful examination to the newborn to evaluate his health.

At birth, the normal weight of the baby varies between 2.5 kg and 4.5 kg. No matter if the baby is heavier or not, it all depends on the mother`s health during pregnancy and her diet during the 9 months.

What Does a Normal Weight Mean?

In the first 10 days at birth, the baby loses 10% of his weight, but he`ll recover it quickly. In the first few weeks after birth, the baby needs to take 175g – 230g per week, so up to the age of 6 months, the baby will double his birth weight.

Still, nothing is certain! Don`t worry if your baby doesn`t take enough weight per week. Babies develop differently, and have period in which they develop more rapidly and others when their development is slower. – More to read!

Infant`s Weight Related to Health Issues

The weight of a newborn is, often but not always, a good signal of his development and health. A smaller weight at birth could indicate an intrauterine infection of the mother or chromosomal abnormalities. The babies that are heavier could mean mothers who developed diabetes while they were pregnant, had congenital heart diseases or they were obese.

As already mentioned, in 3 or 4 days after being born, an infant will lose around 5% to 10% from his weight at birth. This decrease in body weight is mostly because of the fluid shifts. Babies that are heavier lose usually several hundreds of grams. However, if the weight loss is higher than 10%, the baby might have health issues. The water represents around 80% from the body weight of an infant. After his first mouth of life and up to 6 months, the babies will gain around 200g each week.

Newborn Weight Details

Even though the brain of a newborn represents 25% from the brain`s mass in adulthood, his body weight is only 5% from his adult weight. Still, different parts of his body will develop in different proportions. For instance, at birth his head will be heavier than the rest of his body and will remain proportionally smaller in relations with his body.

We all have seen babies, but how many of us really know the characteristics of a newborn? Infants grow in different ways and proportions. Still, the average weight of a newborn is of around 3.4kg. Newborn babies vary in weight from 2.5kg to 4kg. The average weight is mostly for Caucasian newborn babies. Africa or Asiatic infants are smaller in weight at birth. The small difference at birth between these ethnic groups can relate to the stature and age of the parents, but also to the mother`s health and the period of time between births.

What Are the Growth Curves?

You should know that you are among the millions of mothers who are worried about their baby`s weight. One of the most frequent questions that fresh mothers ask themselves is if their baby develops normally. Well, the pediatrician will help you get rid of these fears.

At each visit, the doctor will record the baby`s weight and what waist he has. This will tell you if the little one falls into the normal development values of a child of his age.

It would be best to also have a chart at home with the baby`s height and weight up to 1 year of age. If at one point you notice that his weight is lower or higher than normal, you should ask for an expert`s advice. – Click here!

If you don`t have a growth chart received from the maternity, ask the pediatrician to give you one or you can have one printed from an online resource. You can find many charts online for girls or boys.

The middle line of the chart indicates the average value. Therefore, 50% of children are under that particular value, while 50% are over.

What to Do when He`s Chubby?

As long as the baby grows proportionally in weight and height, everything is normal. Instead, if the weight progresses steadily, you need to make measures. Again, the doctor can come to your help. Anyway, the main decision is to change the diet.

When the baby cries or is agitated, you`re often tempted to calm him by giving him your breast or bottle. If he likes to eat often, it`s normal not to refuse you, although just as good of a solution is to take him in your arms, speak to him, change his clothes and cuddle him. You don`t create him a good habit to always feed him every time he cries.

Don`t change your baby`s diet before talking to a doctor. If you`ll take decisions that are so important on your own, you risk to deprive your little one from nutritional values. The doctor knows best what it needs to be eliminated from the baby`s diet.

Don`t think about breastfeeding him more rarely, meaning to skip a meal of his usual meals, or to dilute his milk formula with water. You should take care of your baby`s needs and always consult a doctor before making a major change in anything that is related to your baby`s necessities.

What to Do When He Has a Low Weight?

Mothers with babies who have a low weight are much more concerned than those with fat babies, because they guide themselves after the old idea that if the baby is fatter, he`s healthier! Nothing more further than the truth! A lot of weak babies are active and perfectly healthy while a lot of fatty babies risk to become obese or diabetic. – Click here!

Many times, the baby is weaker either because he`s active and consumes a lot of calories, either because he inherits his parent`s qualities. Instead, if you notice that for 2 – 3 months, the baby`s weight hasn`t increased, you might think there`s a problem and you should consult the pediatrician.

Again, the basic solution is changing the diet. If you still feed him with the bottle and you think he doesn`t eat enough, ask the doctor if you need to change his formula. Don`t try to give him a more concentrated milk, by putting less water in the milk than usual, because there may be a risk for the baby to dehydrate.

If you haven`t yet started diversifying the diet, breastfeed him or give him the bottle at least 5 times per day. If the baby is older and he`s already 4 months, you may start providing solid foods. Regarding this, ask the doctor`s advice to find out what foods to give him the first time when you start diversifying his diet, how many milk meals you should keep giving him and how often you should insert solid foods in his diet.

There won`t be any benefits coming from a sudden change of the diet, so be patient and always try to take healthy decisions.
