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.
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 a child at the age of three years is usually
five times that of the birth weight. t
POOJA KOTHARIMom of a 8 yr 5 m old boy2 years agoA. The average weight for a 4-month-old baby is 14.2 pounds for girls and 15.4 pounds for boys; the average length (aka height) is 24.4 inches for girls and 25.2 inches for boys. Of course that doesn't mean your 4-month-old should weigh and measure exactly that.
