Track Your Baby’s Growth with My Milk Stash

Monitoring your baby’s weight, length, and head circumference is one of the clearest ways to see how well they’re developing. For breastfeeding and pumping parents, growth data is especially powerful because it shows whether your feeding routine is meeting your baby’s nutritional needs.

My Milk Stash includes a built-in growth tracker that automatically plots your baby’s measurements on official World Health Organization (WHO) growth charts. You’ll see instant percentile rankings and easy-to-read trends over time, right alongside your pumping and feeding history.

What Growth Measurements Can You Track?

My Milk Stash supports the three key measurements pediatricians use to monitor healthy development:

• Weight

Track your baby’s weight in kilograms or pounds. Watching weight gain over time helps you and your pediatrician confirm that your baby is getting enough milk.

• Height/Length

Record your baby’s length in centimeters or inches. Length trends help show overall growth and development.

• Head Circumference

Measure your baby’s head circumference with a soft measuring tape. This is especially important in the early months, as it helps track brain and skull development.

Every measurement you log is timestamped and stored, so you can review your baby’s complete growth history at any time.

How WHO Growth Charts and Percentiles Work

When you add a new measurement, My Milk Stash instantly plots it on WHO growth charts for your baby’s age and sex.

What Percentiles Mean

Percentiles show how your baby compares with other babies of the same age:

• A 50th percentile weight means your baby weighs more than 50% of babies their age.
• A 10th percentile length means your baby is longer than 10% of babies and shorter than 90%.
• A 90th percentile head circumference means your baby’s head is larger than 90% of babies their age.

There is no single “perfect” percentile. What matters most is that your baby follows a steady growth curve over time rather than jumping sharply up or down.

Why My Milk Stash Uses WHO Charts

The WHO growth standards are based on breastfed babies from six countries who grew under optimal health and nutrition conditions. Because of this, WHO charts are considered the gold standard and are recommended by pediatricians worldwide, especially for breastfed infants.

By using WHO charts, My Milk Stash helps you see how your baby’s growth compares to a global standard for healthy development.

How Growth Connects to Feeding in My Milk Stash

What makes My Milk Stash unique is how it links growth data with your pumping and feeding history. Instead of looking at growth in isolation, the app helps you understand how feeding patterns and milk supply relate to your baby’s growth.

With AI-powered insights, My Milk Stash can help you:

• Spot correlations between feeding volume and weight gain

See if a weight gain spike lines up with a period of increased feeding or higher pumped volumes.

• Identify possible reasons for plateaus

If your baby’s growth slows or plateaus, the app can highlight whether this coincides with changes in your pumping schedule, milk output, or feeding frequency.

• Compare growth across feeding styles

Track how your baby grows during periods of exclusive breastfeeding, exclusive pumping, or combo feeding (breast milk plus formula).

These insights can help you have more informed conversations with your pediatrician and make data-backed adjustments to your feeding routine.

When and How Often to Log Measurements

You can log measurements from both doctor visits and at-home checks.

At the Pediatrician

Pediatrician weigh-ins and measurements are typically the most accurate. After each appointment, open My Milk Stash and log:

• Weight
• Length/height

Track Your Baby's Growth in My Milk Stash

My Milk Stash includes built-in growth tracking so you can monitor your baby's weight, length, and head circumference alongside your pumping and feeding data. Having growth data in the same app means you can see the direct relationship between your milk supply and your baby's development — all in one place.

How to Log Growth Measurements

Tap the + button and select Growth. Enter your baby's weight, length, and head circumference. You can log as often as you like — after pediatrician visits, weekly check-ins, or whenever you weigh your baby at home.

Each measurement is plotted on WHO growth charts so you can see exactly where your baby falls in the percentiles. The charts update instantly as you add new data points.

Understanding WHO Growth Charts

My Milk Stash uses the official World Health Organization (WHO) growth standards — the same charts your pediatrician uses. You'll see your baby's percentile for:

• Weight-for-age — is your baby gaining weight on track?
• Length-for-age — how is your baby growing in height?
• Head circumference-for-age — important for neurological development tracking

The percentile curves help you spot trends over time. A consistent percentile means steady, healthy growth. Changes in percentile can be worth discussing with your pediatrician.

Why Growth Tracking Matters for Pumping Moms

For exclusively pumping moms, growth tracking closes the loop. You know how much you're pumping, how much your baby is eating, and now — how your baby is growing. If your baby's weight gain is steady, it confirms your supply is meeting their needs. If growth slows, you can review your pumping and feeding data to identify whether intake changes might be a factor.

Neural Insights™ and Growth

Neural Insights™ can surface observations that connect your feeding data with growth trends. These AI-powered insights give you a more complete picture of how your pumping routine supports your baby's development.
