Introduction
Imagine this: you’re a new mom, carefully pumping breast milk to store for your baby, only to notice it smells a bit… off. Maybe it’s soapy or metallic, and you’re wondering if something’s wrong. Don’t worry—you’re not alone. This could be due to lipase, an enzyme naturally found in breast milk that helps your baby digest fats. Sometimes, lipase is more active, causing these changes. In this guide, we’ll walk you through creating a personalized pumping chart to manage your breastfeeding journey, whether you’re dealing with high lipase or just want a schedule that fits your life. High lipase and pumping challenges are common, and with the right plan, you can feel confident and in control.
What is a Pumping Chart and Why Do You Need One?
A pumping chart is a schedule that tracks when and how often you pump breast milk. It helps you maintain your milk supply, avoid engorgement, and ensure your baby has enough milk. Whether you’re a working mom, exclusively pumping, or building a freezer stash, a chart keeps you organized.
Why does it matter? Breastfeeding is unique for every mom. Some pump every few hours; others need flexibility. A personalized chart adapts to your body’s rhythm and your baby’s needs, making the process less stressful. Plus, it can help you spot patterns—like when your supply peaks—so you can plan better.
What is Lipase in Breastmilk?
Lipase is an enzyme in breast milk that breaks down fats, making them easier for your baby to digest. It’s a natural part of breast milk’s magic, ensuring your little one gets vital nutrients. Without lipase, those fats wouldn’t be as accessible for your baby’s growth.
But what happens when lipase is “high”? High lipase means the enzyme is extra active, causing stored milk to develop a soapy, metallic, or fishy smell or taste after a few hours or days. It’s not harmful, just noticeable. For some moms, this is a surprise when they thaw frozen milk or open a refrigerated bottle.
Why Does High Lipase Happen?
High lipase is often just a natural quirk. Some moms’ bodies produce milk with more active lipase—it’s like having a unique fingerprint. There’s no “one-size-fits-all” reason, but it’s usually not a cause for concern.
Could diet play a role? Some speculate that foods high in unsaturated fats might influence lipase activity, but there’s no solid proof. Lactation stage might matter too—lipase levels can vary early on or as breastfeeding progresses. Hormones could also be a factor, though research is still unclear. What we do know: high lipase isn’t caused by poor hygiene, bad pumping habits, or illness. It’s just how some bodies work.
Is High Lipase Milk Safe for My Baby?
Absolutely, high lipase milk is safe! The nutritional goodness—vitamins, fats, and antibodies—remains intact. Your baby can drink it without any health risks. It’s like choosing between regular or extra-zesty salsa—different flavor, same quality.
That said, some babies are picky. They might scrunch their nose at the soapy taste and refuse a bottle. This doesn’t mean the milk is bad; it’s just a preference. If your baby happily drinks it, there’s no need to change a thing. You’re still giving them liquid gold.
How to Spot High Lipase in Your Milk
Wondering if you have high lipase? The telltale sign is a change in smell or taste after storing milk. Freshly pumped milk usually smells sweet or neutral. High lipase milk might turn soapy, metallic, or fishy after a few hours in the fridge or days in the freezer.
Here’s a quick test: Pump a small amount of milk and store it in the fridge. After 12–24 hours, give it a sniff or taste. If it’s off, high lipase could be the culprit. Don’t worry—this is common, and you’ve got options to manage it while building your pumping chart.
How to Create a Pumping Chart That Works
A pumping chart is your roadmap to breastfeeding success. Here’s how to make one that fits your life:
Step 1: Understand Your Baby’s Needs
Newborns feed 8–12 times a day, about every 2–3 hours. Older babies might need less frequent feeds. Check with your pediatrician to estimate how much milk your baby needs daily (usually 24–36 ounces by 1 month). Your chart should match this demand.
Step 2: Set a Baseline Schedule
Start with a flexible plan. For example:
· Morning: Pump at 6 AM and 9 AM (mornings often yield more milk).
· Midday: Pump at 12 PM, 3 PM, and 6 PM.
· Evening/Night: Pump at 9 PM and midnight.
If you’re working, align pumps with breaks—say, 9 AM, 12 PM, and 3 PM. A wearable breast pump, like the KISSBOBO 1058, can make this easier with its lightweight design and quiet operation, letting you pump discreetly anywhere.
Step 3: Adjust for Your Supply
Notice when your breasts feel full—this signals peak supply times. Pump then to maximize output. If you’re dealing with engorgement or a clogged duct, pump gently to relieve pressure without overstimulating. A chart helps you track these patterns.
Step 4: Factor in High Lipase
If high lipase is an issue, plan to use milk sooner. Pump and refrigerate milk for use within 24 hours, or scald it before freezing (more on that below). Note on your chart when milk was pumped and when it needs to be used to avoid waste.
Step 5: Track and Tweak
Log each session—time, duration, and output (in ounces). Review weekly to adjust. Low output? Try double pumping or adding a session. Baby refusing milk? Test for lipase and tweak storage.
What Can You Do About High Lipase?
High lipase doesn’t have to derail your pumping plan. Here are practical solutions:
Scalding Breastmilk
Scalding deactivates lipase, preserving milk’s fresh taste. Here’s how:
1. Pump fresh milk into a clean container.
2. Heat it in a saucepan to 180°F (82°C) until bubbles form at the edges—don’t boil!
3. Cool quickly in an ice bath (a breast cooler pad can help).
4. Store in breast milk storage bottles glass or free breast milk storage bags.
5. Scalding is ideal if your baby rejects high lipase milk.
Note: It may slightly reduce some vitamins, but the milk stays nutritious. Only scald milk you plan to freeze.
Use Fresh Milk
Feed freshly pumped or refrigerated milk within 24 hours to avoid lipase changes. A pump to bag system, like reusable bags, keeps things simple. This works great for moms who pump daily.
Mix Milk
If your baby tolerates high lipase milk, mix older milk with fresh to dilute the taste. Ensure both are at the same temperature. This can stretch your stash without scalding.
Experiment with Storage
Some moms swear by glass containers for breastmilk storage to reduce odor absorption, though evidence is anecdotal. Test different breast milk storage bags to see what works. Store milk in small portions (2–4 ounces) to minimize waste.
High Lipase vs. Milk Oxidation
Confused if it’s high lipase or something else? Milk oxidation can mimic lipase issues, causing a metallic or rancid smell. Unlike lipase (an enzyme issue), oxidation happens when milk fats react with oxygen, often linked to a diet high in unsaturated fats.
To reduce oxidation:
· Eat antioxidant-rich foods (berries, spinach).
· Store milk in airtight glass milk storage containers.
· Use insulated bag for breast milk to keep it cold.
Your pumping chart can note which milk smells off to pinpoint the cause. If it’s oxidation, adjust storage; if it’s lipase, scalding helps.

When to Seek Help
Most high lipase cases are manageable, but sometimes you need support. Contact a lactation consultant (IBCLC) if:
· Your baby consistently refuses milk, even after scalding.
· You suspect a clogged duct vs. engorgement impacting supply.
· You’re stressed about milk storage or output.
They can review your pumping chart and suggest tweaks, like adjusting flange size guide printable for comfort or trying a best breast pump for inverted nipples.

FAQ: High Lipase and Pumping Charts
1. How do I know if my breast milk has high lipase?
High lipase milk often smells or tastes soapy, metallic, or fishy after storage, even in the fridge for 12–24 hours or freezer for a week. To test, pump a small amount, refrigerate it overnight, and sniff or taste it. If it’s off, it’s likely high lipase. Freeze a small batch for a month and test again to confirm before building a large stash.
2. Is high lipase milk safe for my baby?
Yes, high lipase milk is completely safe and retains its nutritional value. Some babies don’t mind the taste, while others may refuse it due to the soapy or metallic flavor. If your baby drinks it, no changes are needed. If they reject it, try mixing with fresh milk or scalding.
3. How can I create a pumping chart that works with high lipase?
Start by pumping every 2–3 hours (8–10 times daily) to match your baby’s feeding schedule, adjusting for work or lifestyle. Use a handsfreee, quiet, efficient pump like the KISSBOBO 1508, which has hospital-grade suction to empty breasts quickly and a silent design that won’t wake your sleeping baby. Log each session’s time and output, and prioritize fresh or refrigerated milk (used within 24 hours) to avoid lipase changes. Scald milk before freezing if needed.
4. How do I scald breast milk to manage high lipase?
Scald milk right after pumping by heating it to 180°F (82°C) in a saucepan until bubbles form at the edges (don’t boil). Cool it quickly in an ice bath, then store in glass containers or breast milk bags. Scalding deactivates lipase but may reduce some nutrients, so only scald if your baby refuses the milk.
5. What if my baby refuses high lipase milk?
Try mixing frozen high lipase milk with fresh milk (e.g., 75% fresh, 25% frozen) to dilute the taste, gradually increasing the frozen portion. Some moms add a drop of alcohol-free vanilla extract per ounce, though check with your pediatrician first. If refusal persists, consider donating to a milk bank for NICU babies who don’t mind the taste.
6. How is high lipase different from milk oxidation?
High lipase is caused by an enzyme breaking down fats, creating a soapy or metallic taste after storage. Oxidation, often linked to a diet high in unsaturated fats (e.g., fish), causes a rancid or metallic smell due to fat exposure to oxygen. Prevent oxidation with airtight glass storage and antioxidant-rich foods like berries. A pumping chart can track which milk smells off to identify the issue.
7. What can I do with high lipase milk my baby won’t drink?
If your baby rejects it, donate to a milk bank (many accept high lipase milk for tube-fed preemies), use it in milk baths for skin benefits, or mix it into solids like purees when your baby is older (6+ months). Avoid throwing it out—your hard work can still benefit your baby or others.
