Average Weight Of Infants
Babies grow up very fast. Even before you can possibly realize, they grow from a squirming helpless tiny tot to a toddler who can wreak havoc merely in the crawling stage! With time, one needs to change the dietary pattern of the baby and provide all the necessary nourishment. This results in changes in the average weight on infants. Mostly, babies lose around 5-10% of their original weight after birth. A breast-fed baby is usually heavier than a bottle-fed baby, but within the first year, they become thinner. The physical characteristics of a baby then start to develop as inherited from the parents.
In the first 24 months, the growth of the baby is quite rapid, thus leading to fluctuations in the weight. Thereafter, the growth stabilizes and the baby puts on weight steadily. Usually, girls tend to grow at a faster rate than boys, till they reach their teenage. On a general basis, one notices that infant increases in length by almost 30% in the first five months and by about 50% in the first year. The average weight of an infant doubles between the time of birth to five months. Till the age of one year, it increases by three times and by four times till the baby turns two.
