Title: Navigating the Path of Growth: WHO Growth Chart for Breastfed Babies

Welcome to the wonderful world of parenthood! If you’re a new parent, congratulations on embarking on this incredible journey. One of the most important aspects of your baby’s early life is their growth and development. And when it comes to monitoring your breastfed baby’s growth, the World Health Organization (WHO) growth chart is your trusty companion.

In this blog post, we’ll dive deep into the WHO growth chart for breastfed babies. We’ll provide you with all the essential information you need to understand and use this valuable tool to ensure your little one is thriving. So, let’s embark on this adventure together and discover how to keep your baby growing happily and healthily!

Understanding the WHO Growth Chart

The WHO growth chart is a comprehensive and universally recognized tool for assessing the growth of infants and children under the age of five. It’s designed to monitor how well your baby is growing compared to other babies of the same age and sex, particularly when it comes to breastfed babies. Here are the key features of the WHO growth chart:

  1. Breastfeeding as the Gold Standard: The WHO growth chart is unique because it’s based on data from healthy breastfed infants and is considered the gold standard for breastfed baby growth. It’s essential because breastfed babies often grow differently than formula-fed babies.
  2. Standard Growth Patterns: The chart provides a visual representation of growth patterns, including weight-for-age, length-for-age, weight-for-length, and head circumference-for-age. These measurements help healthcare professionals assess a baby’s growth against established standards.
  3. Percentiles: The WHO growth chart uses percentiles to compare your baby’s growth to that of other babies. For example, if your baby falls in the 50th percentile for weight, it means they are right in the middle in terms of weight compared to other babies of the same age and sex.
  4. Z-Scores: Z-scores are another way to analyze your baby’s growth. They express how far your baby’s measurements are from the median (average) in terms of standard deviations. A Z-score of 0 is right at the median, while a positive or negative Z-score indicates being above or below the average, respectively.

Why Is the WHO Growth Chart Important for Breastfed Babies?

Now that we understand what the WHO growth chart is, let’s delve into why it’s so crucial, especially for breastfed babies.

  1. Unique Growth Patterns: Breastfed babies tend to grow differently than formula-fed babies. They may gain weight more slowly initially but catch up later. The WHO growth chart takes these unique patterns into account, ensuring your breastfed baby’s growth is appropriately assessed.
  2. Breastfeeding Advocacy: It supports and promotes breastfeeding as the optimal source of nutrition for infants. By using a growth chart based on breastfed babies, healthcare professionals can provide better guidance to parents who choose to breastfeed.
  3. Early Detection: The chart helps identify potential growth issues early on, allowing healthcare providers to address them promptly. This early detection is crucial for ensuring your baby’s overall health and development.

How to Use the WHO Growth Chart

Now that you understand the importance of the WHO growth chart, let’s discuss how to use it effectively for your breastfed baby.

  1. Consult with a Healthcare Provider: Your baby’s healthcare provider will be your guide through this journey. During regular check-ups, they will measure your baby’s weight, length, and head circumference and plot these measurements on the WHO growth chart.
  2. Tracking Growth Trends: The key to using the growth chart is tracking your baby’s growth trends over time. It’s not just about one measurement but a series of them. By doing so, you’ll get a clear picture of how your baby is progressing.
  3. Ask Questions: Don’t be afraid to ask your healthcare provider questions. They can explain the growth chart, your baby’s measurements, and what they mean for your baby’s health. Your peace of mind is essential!
  4. Remember Individuality: Keep in mind that every baby is unique, and their growth may not follow the exact percentile lines on the chart. What’s crucial is that your baby maintains their growth curve and doesn’t suddenly drop or skyrocket.

Embracing the Unique Growth Curve

Remember, every baby is unique, and the WHO growth chart recognizes this diversity. Your breastfed baby’s growth curve may look different from the chart’s percentiles, and that’s perfectly okay! It’s essential to focus on your baby’s overall health and development rather than comparing them to others.


The WHO growth chart for breastfed babies is an invaluable tool for monitoring your little one’s growth and ensuring they are on the right track. By understanding how it works, consulting with your healthcare provider, and tracking your baby’s growth trends, you can provide the best care and support for your breastfed baby. Remember, every baby is unique, and as long as they maintain their growth curve, you can rest assured that they are growing happily and healthily.


Q1: What if my breastfed baby’s growth falls below the 5th percentile on the WHO growth chart?

A1: If your baby consistently falls below the 5th percentile or experiences a sudden drop, consult your healthcare provider immediately. It may indicate an issue that needs addressing, such as inadequate breastfeeding, underlying health concerns, or poor weight gain.

Q2: Can formula-fed babies also use the WHO growth chart?

A2: While the WHO growth chart is primarily designed for breastfed babies, it can still provide valuable information for formula-fed infants. However, healthcare providers may consider other growth charts designed specifically for formula-fed babies in some cases.

Q3: Is it normal for breastfed babies to have slower weight gain initially?

A3: Yes, it’s normal for breastfed babies to have slower weight gain in the first few months. Breast milk composition changes to meet your baby’s needs, and they often experience a growth spurt around six months of age, catching up in weight gain.

Q4: Can I exclusively breastfeed my baby without any supplements while following the WHO growth chart?

A4: Yes, many babies exclusively breastfed according to the WHO growth chart thrive without any supplements. However, it’s essential to monitor your baby’s growth and consult with a healthcare provider if you have concerns about their nutrition.
