Weight Gain in the second year of life is _____________
The average bih weight of neonates is about 3 kg. During the first a few days after bih, the newborn loses extracellular fluid equivalent to about 10% of the body weight. Most infants regain their bih weight by the age of 10 days. Subsequently, they gain weight at a rate of approximately 20-40 g per day for the first 3 months of life. Thereafter, they gain about 400 g weight every month for the remaining pa of the first year. An infant usually doubles his bih weight by the age of 5 months. The bih weight triples at 1 year and is four times at 2 years of age. Thus, the weight at 5months, 1 year and 2 years is approximately 6, 9 and 12 kg, respectively. The weight of a child at the age of 3 years is approximately five times that of the bih weight. At 5 years, the expected weight can be calculated by multiplying the bih weight by 6, at 7 years by 7 and at 10 years by 10. It follows that the expected weight at 3, 5, 7 and 10 years is approximately 15, 18, 21 and 30 kg, respectively. On an average, a child gains about 2 kg every year between the ages of 3 and 7 years, and 3 kg per year after that till the pubeal growth spu begins.
