Calculate your Baby’s Development

January 8, 2007 by Paul Banas Leave a Comment


Growing babies usually follow a good curve. However, there may be periods when you will notice ‘spurts’ or ‘dips.’ As your baby’s development is dependent on a number of complex factors, this is not usually a cause for worry.


Here is a chart that indicates the height and weight development of your baby*. Consult your doctor if you have concerns regarding your baby’s development.


Neonates



  • Most full-term babies weigh between 2.6 to 3.8 kilos (5 lb, 11 oz to almost 8 lb, 6 oz). They will gain approximately 19 gm (2/3 oz) per day.


  • Full-term babies measure approximately 48–53 cm (19 and 21 inches) long. They will grow by about 2.5–4 cm (1-1½ inches) every day.

Three months



  • Around the middle of the first month after birth, babies grow by about 14-28 gm (½-1 oz) daily.


  • Babies’ length will increase by about 2.5 – 3.7 cm (1-1½ inches) in a month.

Between 4 to 7 Months



  • A baby may start taking solid food during this phase.


  • Babies at this age grow by approximately 0.4-0.5 kg (1 to 1.25 lb) per month.


  • Babies’ length may increase by about 5 cm (2 inches) in this period.

Between 8 to 12 months



  • Most babies become mobile during this period.


  • 8-month-old babies weigh around 6.3-8.1 kg (14 to 18 lb); an even wider range is considered normal.


  • At the end of 12 months, most babies may approximately triple their weights at birth.


  • They may measure approximately 70-80 cm (28 to 32 inches) long.
