By the 6th month, the baby's weight will usually be twice that of birth and the baby's height will increase by about 15cm compared to when it was born.

On average, babies gain weight very quickly in the first 3 months (1,000 - 1,200g/month), in the next 3 months, they gain weight from 500-600g/month, and in the next 6 months, they only gain weight from 300-400g/month. The phenomenon of children not gaining weight at 6 months is quite rare.
By 6 months, your baby will have doubled his pre-birth weight. However, the specific weight index of each baby will vary, depending on the child's sex or other factors. If the mother takes care of the baby properly, the standard 6-month-old baby's weight will be:
6-month-old baby boy weighs about 7.1 - 8.9 kg 6-month-old girl weighs about 6.5 - 8.3 kg

Parents need to understand the factors that affect the physical development of their children in order to have a better orientation to raise their children, to help them grow stronger and taller. Key factors include:

However, children's height is usually only affected by about 23% from genetic factors.
