About MapMyKidz
Professional Child Health App for Growth, Development & Wellness. Track growth, monitor milestones, access vaccination schedules, nutrition guidance, and expert health insights using medical standards.
About the Founder
Dr. Aravind Venkatesh Sreedharan is a paediatric endocrinologist dedicated to empowering parents with clear, actionable insights into their child's health. With extensive experience at KK Women's & Children's Hospital and a strong foundation in digital health and clinical leadership, he has seen first-hand how early detection and timely guidance can transform a child's growth, health and wellbeing.
Driven by this belief, he founded MapMyKidz to bring personalised, intuitive, and data-driven health support directly to families. His vision is simple: to make every child's health journey visible, understandable, and proactively managed—so parents feel confident, informed, and supported at every step.
Growth Assessment
Track your child's height, weight, BMI, and growth patterns using WHO and CDC standards. Newborn birth assessment (weight, length, head circumference) using INTERGROWTH-21st standards.
Vaccination Schedule
Access vaccination schedules tailored for Singapore, India, and US, with country-specific guidelines and recommendations.
Expert Library
Explore development milestones, growth articles, vaccine information, and child health resources for every stage of your child's journey.
Privacy & PWA
All calculations are performed locally on your device. No data is sent to external servers. Works offline as a Progressive Web App.
How Growth Assessment Works
CDC and WHO Growth Standards
MapMyKidz uses internationally recognized growth standards for three key measurements:
- Length/Height-for-age: WHO standards and CDC charts
- Weight-for-age: WHO standards and CDC charts
- Nutritional Status: Weight-for-length and BMI
LMS Method
We use the LMS (Lambda-Mu-Sigma) method for precise calculations:
- L (Lambda): Skewness parameter
- M (Mu): Mean value
- S (Sigma): Coefficient of variation
Length/Height-for-Age Measurements
Length/Height-for-age charts track how your child's measurements compare to other children of the same age and gender:
- WHO Length-for-age (0-2 years): Based on healthy, breastfed children from diverse populations
- CDC Height-for-age (2-20 years): Based on large-scale surveys of US children
Mid-Parental Height Calculation
Estimates your child's expected adult height based on parental heights:
- Boys: (Mother's height + Father's height + 13 cm) ÷ 2
- Girls: (Mother's height + Father's height - 13 cm) ÷ 2
Weight-for-Age Measurements
Weight-for-age charts track how your child's weight compares to other children of the same age and gender:
- WHO Weight-for-age (0-2 years): Based on healthy, breastfed children from diverse populations
- CDC Weight-for-age (2-20 years): Based on large-scale surveys of US children
Nutritional Status Analysis
For children 0-2 years, we use weight-for-length (WFL) measurements. For children 2-20 years, we use Body Mass Index (BMI):
- Weight-for-length (0-2 years): WHO standards for healthy growth assessment
- BMI Formula (2-20 years): BMI = weight (kg) ÷ height (m)²
- CDC BMI-for-age (2-20 years): Charts for monitoring body composition
Interpreting Results
Length/Height Interpretation
Length/Height percentiles show how your child's measurements compare to other children of the same age and gender:
Mid-Parental Height (MPH) Target Ranges (2-20 years)
For children 2 years and older, we calculate target height ranges based on your child's genetic potential (mid-parental height):
Weight Interpretation
Weight percentiles indicate if your child is underweight, normal weight, or overweight for their age:
BMI Interpretation
BMI percentiles measure body composition relative to height and age:
Z-Scores
Z-scores show how many standard deviations your child's measurements are from the mean. They're particularly useful for extreme values (below 3rd percentile) and provide more precise measurements than percentiles alone for height, weight, and BMI.

The INTERGROWTH-21st Project was a multi-centre, multi-ethnic, population-based project, conducted between 2009 and 2014, in eight demarcated urban areas: Pelotas, Brazil; Shunyi County, Beijing, China; Central Nagpur, India; Turin, Italy; Parklands Suburb, Nairobi, Kenya; Muscat, Oman; Oxford, UK, and Seattle, USA.
Its primary aim was to study growth, health, nutrition and neurodevelopment from less than 14 weeks of gestation to 2 years of age, using the same conceptual framework as the WHO Multicentre Growth Reference Study, so as to produce international prescriptive standards for pregnancy dating, maternal weight gain, fetal growth, newborn size, the postnatal growth of preterm infants and cognitive development at 2 years of age.
These scientifically robust clinical tools may be used to monitor and evaluate maternal and fetal wellbeing, as well as infant health and nutrition at an individual and population level.
