Let’s talk about something you might not have expected on your pumping journey: a strange (but totally normal) smell in your breast milk.Yep, it happens and here, nothing is off-topic and nothing is too embarrassing. We talk about it all, because you deserve real answers without judgment. If you’ve recently started breast pumping and noticed a change in the smell of your milk, you’re not alone and you’re not doing anything wrong. A common reason behind this surprising scent is high lipase activity.

Lipase is a natural enzyme in breast milk that helps break down fats, making it easier for your baby to digest. But when lipase levels are a bit higher than usual, the enzyme can start working quickly especially once milk is expressed and sits at room temperature or is stored.

This can cause your milk to take on a soapy, metallic, or fishy smell over time. The odor is most noticeable in stored milk or milk that’s been sitting out. No need to worry, milk with high lipase activity is still completely safe and healthy. Some babies don’t mind the smell or taste, while others might be more sensitive to it and refuse it. Breastfeeding and pumping come 

with unexpected moments and questions you might not even know you’d have, nothing is weird, nothing is gross, and nothing is off-limits.
