Question

Accepted Answer

the average birth weight of neonates is about 3 kg. 
during the first few days after birth, the newborn loses
extracellular fluid equivalent to about 10% of the body
weight. 
most infants regain their birth weight by the age of 10 days. subsequently, they gain weight at a rate of
approximately 25 to 30 g per day for the first 3 months of life. 
thereafter they gain about 400 g weight every month,
for the remaining part of the first year. x
an infant usually doubles his birth weight (taken as 3 kg) by the age of 5 months. the birth weight triples at 1 year and is four times at 2 years of age. 
the weight of ca child at the age of three years is usually
five times that of the birth weight.
