You’re not alone. Many parents hear that the secret to weight gain is getting to the fatty hindmilk. Here’s what the research and lactation experts actually say.
Foremilk vs. Hindmilk – What’s Really Happening
- Every feed starts with foremilk (the milk that comes first) and gradually transitions to hindmilk (the milk that comes later).
- This is not like skim vs. whole milk. Fat content changes gradually—there’s no exact “switch” you can time.
- Foremilk isn’t automatically low fat, and hindmilk isn’t automatically high fat. Fat content can vary from feed to feed, even during the same day.
Feeding Length and Milk Fat
- Longer feeds often mean more letdowns and slightly higher fat content as the feed continues.
- But this doesn’t mean that shorter feeds are “bad” or that babies are missing out.
- Trying to force a baby to stay on one breast for a certain amount of time to “get hindmilk” can sometimes reduce overall intake instead of helping.
What Really Matters for Weight Gain
- Total daily milk intake is what drives healthy growth—not individual feeds or chasing hindmilk.
- If your baby isn’t gaining as expected, focus on increasing overall milk intake and checking for any feeding challenges.
- Each day and each feed can look different. The goal is consistent, effective feeding over time.
Practical Tips
- Skip the “hindmilk hacks.” Instead, aim for frequent, effective feeds.
- Make sure your baby is transferring milk efficiently at each feed.
- Keep track of overall growth trends, not just the length of individual feeds.
