The average full-term infant weighs 3.5kg at birth. Few babies weigh less than 2.5kg or more than 4.5kg.
When a baby’s weight is below 2.5kg, the baby is tagged underweight. When it is above 3.5kg, it is tagged overweight. But the underweight is deadlier.
What Are Factors Responsible?
A baby’s birth weight depends on a number of factors, including;
– Size and Ethnic origin of the parents. Small parents tend to have small babies. According to findings, in the UK, Asian infants tend to be smaller than the white or black infants.
– Baby boys weigh, on average, slightly more than baby girls.
Babies that weigh less than 2.5kg at birth are classified as being of low birthweight.
– Premature babies, born before the 37th week of pregnancy, usually have low birthweight.
Other factors that may be responsible are, if the baby is undernourished while in the uterus, where the placenta was insufficient. May be as a result of pre-eclampsia or heavy smoking during pregnancy.
Diabetic pregnant women, also, usually give birth to overweight babies.
Babies are usually weighed after birth as soon as they are cleaned and stimulated. A underweight child tend to be hypothermic, which is very dangerous, and may not be able to thrive well, IF care is not taken.
