Ideal weight for infants
A great deal of anxiousness is observed by parents on the ideal weight of infants. Babies who are born between 37 to 40 weeks generally weigh anywhere between 2.5 kg and 4 kg.

When you go for regular check ups, you can easily comprehend the ideal weight for infants.

Facts About Ideal Weight for Infants

There are different factors which have a great impact on the weight of the infants and they include genitive, health history and eating habits of the mother and her temperament. However, weighing the baby at birth time is essential to track the baby’s weight in the future.

  • During first three to four days, the baby loses around 7% to 10% of his body weight. However, this 10 percent loss will be gained by the baby during the second week. After breast feeding for six months, the baby gains 2 pounds of weight every month
  • Weight of new-born babies increases two times once they become 4 months old. After twelve months, that is, after or around the first birthday, you can expect his weight to be tripled
  • During the first 2 years, the growth of the baby will be quite rapid and this will lead to fluctuations in the ideal weight for infants. After 24 months, the growth stabilizes and the baby will put on weight in a steady manner

Factors That Affect Ideal Weight for Infants

There are many factors that contribute to a low birth weight of a baby as mentioned below:

    1. Inherited Medical Condition A baby can inherit potential hereditary diseases in the womb itself, and this may lead to having a low birth-weight baby
    2. Term Completion: Pre-term babies and pre-mature babies are mostly born underweight. This is because the baby did not develop fully in the womb, and since babies put on weight only during the later stages of pregnancy, this stage gets missed
    3. Genetics: Though the mother’s weight actually impacts the weight of the baby on birth, his father’s weight also has some impact. Hereditary forms a equation in the baby’s birth weight. Some babies are simply small as it runs in the family
    4. Age at Conception: For all we know, women after the age of 35 tend to have larger babies. Teen pregnancies generally produce babies who are underweight
    5. Pre-pregnancy Weight: A BMI less than 19 is likely to account for a low weight baby, whereas a BMI greater than 24 risks the delivery weight of the baby to be quite large
    6. Multiple Births: Babies may be born relatively smaller in case of multiple-births as babies share the same uterus

  4. Placental Problems: Conditions like pre-eclampsia can reduce the blood supply to the baby, thus restricting the baby’s growth in the womb. Such babies are usually on born low weight because of the deficiency in nutrients and oxygen in the womb
  5. Mother’s Health: If the mother has any unhealthy habits such as drinking and smoking, it may lead to a reduced birth weight of the baby
  6. Gender of the baby: Slight differences between weights might be observed depending on the gender of the baby. Girls are usually smaller and boys heavier
  7. Parents’ birth weight: Parents’ birth weight also affects the birth weight of the baby, though mother’s birth weight seems to be more significant

Premature babies are generally born underweight, and are classified as being born with a “low birth weight” or a “very low birth weight”.
