Use an infant growth chart, WHO growth chart for boys, WHO growth chart for girls and head circumference chart plus a growth rate calculator to monitor your baby's progress.
These growth charts help doctors see if a baby needs supervision.
It makes it easier to decide if the child is following his normal growth increase and take appropriate action.
When looking at an average length/height in different parts of the world; They vary a whole lot.
There are many things that play a roll, like genetics, heritage, illness etc.
But for babies to reach their inborn growth potential, their nutritional intake is the most important.
Babies and children who grow very slowly and are not following their growth chart, need to be examined for eventual food intolerance or other conditions that may hamper infant growth and health.
However during the first year in a baby's life, it is first and foremost the nutrition, that is most important for the baby's physiological growth.
It's good to know what the growth factors are that impact how infants grow in length, head circumference, and then finally the weight.
A baby's weight gain doesn't inform how the baby grows in length and doesn't show the increase in head circumference which is important.
The baby's growth and health after birth, is also dependent on a mother who has prepared herself for motherhood during pregnancy, by eating healthy nutritious food and avoiding all substances, that may be harmful for her baby's development.
During the first year a baby needs regular visits to the doctor's office to check on it's development, head growth, body length, and baby weight gain..
The baby also needs Immunizations.
The World Health Organization, WHO standards provide a better description of physiological growth in infancy.
The WHO growth charts are standards. They identify how the WHO standards are based on a high-quality study designed for creating growth charts.
The WHO standards were constructed using length and weight data measured at frequent intervals starting from birth.
The WHO charts below, show how babies should grow, when they are provided optimal conditions: breastfeeding and a safe environment.
WHO charts show optimal growth which CDC charts don't do.
The Center for Disease Control(CDC) charts show how all infants grow in USA, under good and not so good conditions.

The calculator requires gender (male or female), birth date of child and length to be entered.
1 Percentile Calculated using standard normal distribution
2 Age of child in years, months and days.
3 Length of the baby in metric units of centimeters.
4 Graph Plot Length versus age graph with 5, 10, 25, 50, 75, 95 and calculated percentile lines.
A percentile of 50% represents the average or main length.
A value below 50 percent means a baby measures less than the average infant.
This calculator provides your baby's length or height percentile based on age.
The percentile shows how your infant's length compares to other infants.
The percentile tells you what percentage of babies measure less than your baby.
For example out of a sample of 100 babies, a percentile value of 45 percent means your baby measures more than 45 babies on average.
A value greater than 50 percent means a baby is above average.
This does not mean your baby is over length or under length.
A doctor or physician should be consulted to determine length status.
