Does breast milk go bad? My mother-in-law says one thing, I read something different.

It's frustrating when you disagree with your mother-in-law, but don't worry about this one—you can feel confident.
Breast milk doesn't "go bad" or lose its nutritional value. As long as it's expressed and stored properly, it stays valuable for your baby. Over time, its makeup changes to match your baby's needs—for example, as you keep nursing, the fat content goes up, which helps your baby feel full. So the milk's texture and color might look different, but that's not spoilage; that's your body adapting for your baby.
Stored breast milk only becomes a problem in two cases:
- Left at room temperature more than 4 hours (below 25°C)
- Stored in the fridge longer than 4 days or in the freezer longer than 6 months
Outside of those windows, properly expressed and stored milk is still your baby's most valuable food. And while you're nursing, your body keeps making fresh milk—it never runs out—your body makes as much as your baby needs. The difference between what your mother-in-law said and what you've read might be about storage times or how the milk looks. If you're noticing a real drop in supply (baby's not gaining weight, fewer wet diapers), see your pediatrician. But just about whether milk "goes bad"—no, it doesn't; use it confidently.
