Baby rapidly grows from the day of birth. Most babies weigh about 3333 g at birth (approximately 7 lb 5 oz). This doubles by the age of six months, and trebles at 12 months. In the second year, the baby will gain about 3.5 kg (about 7% lb), and another 2.5 kg (about 5% lb) in the third year. From this point on, the child will gain about 2.5 kg each year until reaching the period known as puberty. At this time, enormous internal hormonal changes suddenly occur, and there is a wondrous growth spurt as the child sails into adolescence and later into early adulthood.
Baby’s height also increases. This is very rapid in the first six months, after which the rate tends to slow down. Many factors play a part in the individual’s ultimate height. Inherited genetic factors, general health and many environmental considerations all come into play.
But how does the average Australian baby develop month-by-month in the early days? Here is a general guide as to what you may expect during the first six months. Every baby, being an individual, will differ. But the general development usually occurs along these lines. Do not be alarmed if your child does not measure up to this pattern exactly, for differences are often considerable. Conversely, the child may seem to be developing at a much faster rate. But in the long term, it all averages out. The great majority finally fit into the norm which makes up the average Australian child, and finally the average Australian adult.
You might wish to keep a record in the margins of this book of the age the baby achieves each milestone. Also, add any other activities you notice. Later on, especially if other babies follow in your family, you will have a record of the child’s development that can be compared with others to lessen parental worries.
