Factors That Affect The Weight Of A Newborn


A normal gestation period is considered from 38 to 42 weeks. Any newborn that is born before 37 weeks is known as a premature baby and the infants that are born after 42 weeks are called postmature babies.

  • Genetics: Genes can play a crucial role in affecting the birth weight of newborn babies. 50% of the genes in a newborn come from their mother and the rest 50% comes from the father’s gene pool. So there has been a correlation between the height and weight of parents and newborn weight gain.
  • Gender: Even though the difference is minimal, the weight of a male newborn and a female newborn will be different. Male newborn tends to be heavier than their female counterparts.
  • Duration of the pregnancy:  The length of the pregnancy and the weight of the newborn have close links. Studies show that newborns gain weight in the latter phases of pregnancy. So if a baby takes birth prematurely, it lacks the proper growth from the womb and tends to be smaller. If a baby is born after the due date, the heavier it will be.
  • The health of the mother: This is one crucial component that determines the weight of the newborn. If the mother tends to have any medical conditions, it can affect the weight of the newborn. Also, if the mother is under any medications, it can impact the newborn weight.
  • Pregnancy diet: Diet during pregnancy can have a major role in determining the weight of the newborn. If the mother is malnourished and lacks any nutrients in her diet, it can influence the baby’s weight and cause lower weight. If the mother eats healthy or follows an ideal diet and is well-nourished, it can positively affect the weight of the newborn, and thereby the baby is born with a larger-than-average weight.
  • Mother’s habits:  The lifestyle and habits of a mother have a crucial connection with the weight of the newborn. If the mother has habits like smoking, drinking, and doing drugs, chances for the baby to become lower in weight are high.
  • Order of the birth: In many instances, it is visible that the firstborns have a comparatively lower weight than the subsequent children. The second and third children tend to be having more weight than the first child.
  • Stress:  Recent research has shown that stress can affect the weight of the newborn. If the mother is subjected to any kind of stressful events or any kind of abuse during the pregnancy, the weight of the newborn tends to be lower than average.
  • Race: Race can also play an important role in the weight of the newborn. Babies of European descent seem to have considerably more weight than babies of Asian or Indian descent.

How to check the weight of your newborn?


The weight of your newborn is measured continuously if you are still at the hospital. When the infant is discharged and 48 hours have passed, the weight is again calculated. In many cases, the weight of a newborn is measured after one week of birth and in some cases, two weeks after birth. If your baby has any medical conditions it is necessary to check its weight frequently. You can use a weighing scale to measure the weight of the infant. If you don’t have a weighing scale, you can also use some other methods.  A newborn should have at least 5-7 wet diapers after the first week. Also, take care of whether the baby is feeling full after breastfeeding and demanding more. By these measures, you can take into account the ideal weight of the newborn.

Top reasons that create a slow weight gain in newborns


Many reasons can constitute slow weight gain in your newborns. A proper medical evaluation from your pediatrician can reveal the exact reason behind a slow weight gain in newborns. Still, there can be some other reasons that can result in the slower speed of weight gain in babies. Some of them are listed below:

  • Shorter sessions of nursing: Around 8-10 minutes is compulsory to breastfeed a newborn on each side. If the session of nursing is short, the chance to gain weight is reduced.
  • Injury or pain in the baby: If your baby has some sort of wound or injury on its lips, it won’t be able to feed properly.
