Dr Vandan H KumarFather of a 7 yr 4 m old boy1 Year agoA. around 7kg
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.
RashmiMom of a 11 yr old girl1 Year agoA. We just calculate on the basis of birth weight it should be somewhere around 56 to 5700 g but in general standard by the age of seven months a child should be 7 1/2 kg little more so we only go by birthweight we should be the minimum gain that your child should show
