During the first month, your physician will closely monitor your baby weight gain. They will also measure the length and circumference of the head. The way to measure the circumference of the head is to start at a certain point on its forehead. The average weight of a newborn is 3.5 kgs (7.5lbs), although 2.5 kgs (5.5lbs) to 4.5 kgs (10lbs) is also average. In most cases, the boy child is heavier than the girl. It is also true that the later siblings are heavier than the first child.

Newborns will lose weight in the first 4 to 5 days. The baby scale and baby weight will start going up in about two weeks. Ensure your baby is getting the best baby food, which in most cases, is breast milk. It is highly advisable you exclusively breastfeed the baby for about six months.

Many new mothers wonder how much breast milk a newborn should eat. Research shows that you should breastfeed your child at least ten times in a day. After every three to four hours, ensure your baby suckles.

Why Is Baby Weight Important?

One crucial reason why the average newborn weight is recorded is that weight has a direct link to the baby’s survival. Generally, the lower the weight of your child, the more the risk the baby has of infant mortality.

Additionally, the weight of the infant has a direct relationship with later health outcomes. Several conditions, including low IQ, Asthma, and hypertension, are extensive in kids who were born small. In many countries, there are interventions to increase the average baby weight to improve infant mortality.

In their first year, babies with low birth weight (LBW) are twenty times more likely to die than healthy weight kids. When your child has normal baby weight, it usually shows that they have developed fully. The death of infants is low, especially in developed countries. For this reason, researchers need an indicator for this risk. Low weight at birth serves this purpose well.

`Low birth weight is entirely preventable by eating the best baby food during your pregnancy. The prevention of LBW is also a subject for research for many public health policy advisors and pediatricians.

Factors Affecting Birth Weight

Several reasons are associated with low birth weight. They include stress, maternal smoking, and poor economic conditions. The most dangerous is maternal smoking, which is associated with a five percent reduction in average newborn weight. Researchers came with this figure after adjustments in maternal height, baby’s sex, and gestation.

The psychological and socioeconomic conditions had very insignificant relation to normal baby birth weight. Nonetheless, several other factors affect the average birth weight of infants. They include the following.

  • Age of the parent – research shows that women who are over thirty-five years have large babies, whereas teenage pregnancies tend to have underweight babies. It is important to note that the ideal baby weight for normal delivery is three and a half kilograms.
  • Genetics – the weight of the mother, has a direct impact on the weight of the baby. The father’s weight, too, might have some effect. Some babies are small because it is in the family.
  • Twins – if you are having twins, it will harm the baby weight percentile. The babies will be smaller as they share a uterus.
  • Early births – if you have a premature birth, the baby will not be fully developed. Babies add most of their weight during the latter stages of pregnancy.
  • Gender – baby boy weight charts show that boys are generally heavier than girls.
  • Diet during pregnancy – if the mother does not observe the right nutrition, the infant’s weight gain will be significantly affected. A poor diet will lead to underweight babies.
  • Mother’s medical issues – any disease during pregnancy will significantly affect the infants’ weight. Conditions like diabetes and anemia mean the baby will not add weight and may be born underweight.

Healthy babies can be of different sizes. However, the way they develop tends to be very predictable. Your physician will look at the child’s weight, height, and age to determine if the child develops as expected.

The average weight of a healthy newborn is seven to seven and a half pounds (3.5 kgs); low birth weight is any weight below five pounds (2.5kgs), and a larger than average birth weight is any weight above eight pounds (4 kgs). The baby girl weight chart shows they are mostly lighter than the boys. If the baby scale reads below two and a half kilograms, you need to see a doctor. Underweight babies have a high mortality rate.

The Expectation of Baby Weight Gain

If your baby was born at a normal weight, then there are no reasons to keep weighing them. As long as the baby is acting normally and is eating normally, then they are fine. Your pediatrician will place them on a baby scale and check their weight every time you visit the hospital.

However, if your baby scale indicates too low at birth, or you have any concern about the baby not gaining weight, talk to your doctor. The baby weight chart is a good indicator of how the baby is growing, and it usually varies from child to child.

Why Do Babies Lose Weight After Birth?

The truth is that nearly all infants will lose weight after they are born. Typically, the loss of weight will be of grave concern to any parent. The question on most parents’ minds is why their babies lose this weight. Most of the body weight that is lost is fluid.

The weight loss occurs because the tummy is small, and they cannot hold too much milk. Nonetheless, as the baby grows, the belly expands, and they can hold onto much more fluid. How much breast milk should a newborn eat will depend on their weight and tummy size?
