Growth is complex. It depends on a whole number of interacting factors, such as the amount and quality of food, genetics, whether the child's various organ systems are functioning well, the adequacy of the hormones controlling aspects of growth, a child's emotional well-being and environment.
Babies grow at their own rate and the figures below are
meant only to serve as an indication.
If you are concerned about your baby's weight or growth in general, discuss your worries with your child's doctor.
The majority of babies born full-term ,
i.e. 40 weeks, weigh from just over 2.6 to 3.8 kilos (5 lb, 11 oz to almost
8 LB, 6 oz), and they are between 48 - 53cm (19 and 21 inches) long.
A newborn will gain weight at a rate of approximately 19 gm (2/3 oz) per day and grow about 2.5 - 4cm (1 - 1½ inches) during the first month. Most newborns go through a period of rapid growth (a growth spurt) when they are 7 to 10 days old and again between 3 and 6 weeks.
First 3 Months
After losing some of their birth weight during the first few days of life, most babies will then continue to grow steadily. By the middle of the first month, weight gain should be about 14-28gm (½ - 1oz) per day. This increases to, on average, 0.45 - 0.9kg(1½ - 2 pounds) following the first month.
Increases in length during this same period may be about 2.5 - 3.7cm (1 - 1½ inches) per month.
It is usually during this period that solid foods are introduced into
the babies diet.
The variables affecting growth, especially weight, in this period are
many. For example, most babies now move around on their own, and are showing
increasing proficiency at handling solid foods.
During the 2nd year of life, increases in weight decrease with most babies
gaining between 1.4 - 2.3kg (3 - 5lb). By their second birthdays, most
are losing that baby look and growing taller instead of rounder.
