baby weighs 5.5kgs in 20th week is ok

Babies change so fast. In the first year of life, a baby will triple her birth weight, increase her length by 50%, begin to grow teeth, learn to crawl then walk and maybe even say her first words. Since she changes so much in such a short amount of time, how important is her birth weight? What is a Normal Birth Weight? Most full-term newborns (born at between 37 and 40 weeks) will weigh between 6 lbs, 2 oz (2,812 grams) and 9 lbs, 2 oz (4,173 grams), and be anywhere from 19 to 21 inches long (48 to 53 cm). Most babies will lose a small amount of weight soon after birth. This is due to excess fluid at birth, and isn’t a cause for concern. If, however, your baby loses too much weight, that might be an indicator of a health problem and she will need to be monitored by a doctor. Weight and size gain is a very good indicator of health in newborns. Your baby’s weight and size will be carefully monitored in the first few months of life. A baby who is growing well is considered to be generally healthy, while poor growth can be a sign of problems. Low Birth Weight? Babies who are born weighing less than 3 lbs, 4 oz (1,500 g) are considered very low birth weight. Only about 1.5% of babies are born this small. These babies will appear very thin, and their skin will likely be very pale or translucent. High Birth Weight and Large for Gestational Age.. A baby born weighing 8 lbs, 14.8 oz is considered high birth weight, also called macrosomia. Since this falls within the normal range, it is not usually a cause for concern. More troublesome are babies born large for gestational age (LGA). Full-term male babies weighing more than 9 lbs, 3 oz (4,200 g) and females weighing more than 8 lbs, 9 oz (4,034 g) are considered LGA.
