Standard Height and Weight Charts

Do you know that between 3 to 7 years of age, an average child gains around 2 kg’s every year? After that, the baby gains around 3 kg’s per year till the pubertal growth spurt begins.

WHO Standard Height and Weight Chart for Babies

The World Health Organization growth standards are based on accurate results on breastfed and healthy babies. These charts more accurately show how a normal baby should grow. The following chart shows child growth standards that were developed using the data collected by World Health Organisation (WHO)

Let ByGrandma explain to you how to interpret the growth charts.

As you can see, the below charts contains 5 percentiles – 3% , 15%, 50% (Median), 85%, 97%

The lower end of the normal range indication is shown in 3rd percentile line. That is 3% of the normal infants and toddlers will be below the 3rd percentile.

Now, 50% of the population will sit on the 50th percentile (Median).

The upper end of the normal range that is actually 3% of the normal infants and babies will be above the 97th percentile.

The point is, anywhere between the 2nd and 98th percentile is appropriate growth.

WHO Weight Chart for Girls

Let’s discuss with an example with the image above

Girl Baby A’s birth weight was 2.6 kg, you can see the above chart it comes under the 15%

After the completion of One year, the baby weighs 7.6 kg

Interpretation –  I would say the baby has a normal growth and weight gain as she has followed the percentile line.

Oh! Don’t worry. These charts are from the World Health Organisation. So you can be assured of the authenticity of the reports.

Please don’t be concerned if you don’t find an appropriate increase in weight over 1 week. You need to see in the long run that is, what happens over 3 months.

For example: According to the WHO Weight Chart if you see the baby is less than 7.8 kg’s then you should be worried and immediate precautions and checkup’s need to be done.

Now, what if unfortunately, the baby is Underweight? Any precautions? Any remedies?

In case the baby is underweight, first get the baby checked by a pediatrician to rule out any medical symptoms and issues. But there are various reasons for your child not gaining as the kid next door. One of the most crucial reasons can be Heredity. If your partner or you were lean-thin, then please don’t expect your kids to be chubby 

Some kids can be very active or have a high metabolism and don’t gain considerable weight despite eating well. But sometimes, the parents feed the children with sugary and sweet items in hopes of making them gain weight. Please DON’T DO IT. It’ll make your baby obese in the coming years.

To maintain the weight of your baby it is very important to maintain a normal and consistent food right from the day your baby is born until your baby is of 2 years.

Apart from what Grandma suggests, listing foods which will help babies to gain weight.

  • Breastmilk – Undoubtedly the best and healthy food for your baby. It’s rich in fats and the best for your baby’s weight gain. It’s highly suggested to continue breastfeeding your child as long as your baby wants.
  • Eggs – Great for weight gain. You can introduce egg yolk after 10 months. But please have a word with your doc!
  • Khichdi – It is a wholesome meal of lentils and rice and is great for healthy weight gain.

Lastly, few pointers from Grandma to assess the growth of your baby 

  • Please keep doing a regular, periodic check on the progress of your child’s weight and height. So, its important to baby height and weight chart regularly.
  • It is more appropriate than making a single recording of the parameters at any single point in time.
  • You should be weighing the baby monthly intervals during the first year. Every two months during the second year and thereafter every three months up to the age of five years.

Remember, as long as the baby is healthy, active and developing normally it really doesn’t matter if the weight or height fluctuates a bit here and there. As Grandma suggests, don’t get obsessed with the scale. Rather enjoy this beautiful time with your baby!
