Growth charts are essential tools for tracking your child’s development, measuring height, weight, and head circumference over time. For Kiwi parents, these charts are crucial for monitoring their baby’s growth and ensuring they are developing healthily.

Understanding NZ Baby Growth Charts

growth chartsGrowth charts are designed to show how your child is growing, using different measurements such as weight, height (or length), and head circumference. These charts are essential tools for New Zealand parents to track their child’s development accurately.

The Well Child Tamariki Ora My Health Book that parents receive when their child is born includes these important baby weight charts and growth charts, specifically tailored for NZ children. Additionally, downloadable versions are available from the Ministry of Health official website, making it easier for parents to stay informed and proactive about their child’s growth.

Types of Growth Charts

The growth charts available for NZ children include:

  • Weight Charts: These track your baby’s weight over time, helping you ensure they are gaining weight at a healthy rate.
  • Height Charts: These measure your child’s height or length, providing insights into their growth pattern.
  • Head Circumference Charts: These monitor the growth of your baby’s head, which is crucial for tracking brain development.

Growth charts use percentiles to compare your child’s measurements with those of other children of the same age and gender. For example, if your child is in the 50th percentile for weight, it means they are heavier than 50% of children their age and lighter than the other 50%. These percentiles help you understand where your child stands in terms of growth, but it’s important to remember that healthy children can fall anywhere on the chart.

The Well Child Tamariki Ora My Health Book contains 10 growth charts suitable for use with New Zealand children up to 5 years of age.

They are based on measurements collected by the World Health Organization in six different countries and their format is adapted from growth charts used in the United Kingdom. You can also download the current growth charts for New Zealand children from the Ministry of Health website. The growth charts are divided up into the following charts:

Baby Boys:

  • Boys weight 0–1 year
  • Boys weight 1–5 years
  • Boys length 0–2 years
  • Boys height 2–5 years
  • Boys head circumference 0–2 years

Baby Girls:

  • Girls weight 0–1 year
  • Girls weight 1–5 years
  • Girls length 0–2 years
  • Girls height 2–5 years
  • Girls head circumference 0–2 years

What the Lines on the Chart Mean

When looking at growth charts, it’s important to focus on your child’s consistent growth patterns rather than their specific percentiles. These charts are designed to show a range of healthy growth rates, represented by different percentile lines.

Percentiles indicate where your child’s measurements fall compared to other children of the same age and gender. For example, if your child is on the 25th percentile for weight, it means that 25% of children their age weigh less, and 75% weigh more. Similarly, the 50th percentile represents the median, where half of the children weigh more and half weigh less.

What to Do If You Have Concerns

It’s natural for parents to have concerns about their child’s growth and development. If you notice any sudden changes in your child’s growth pattern, or if they are consistently on a much lower or higher percentile, it’s important to discuss these concerns with your Well Child nurse or doctor.

Your Well Child nurse or family doctor. can help you understand the growth charts in more detail and assess whether your child’s growth is within a healthy range. They can provide guidance and support if any issues arise, ensuring your child receives the care they need.

Remember, you know your child best. If something doesn’t seem right, trust your instincts and seek professional advice. Early intervention can make a significant difference in addressing any potential growth or developmental concerns.
