Does breastmilk spoil—I'm really confused about this, what should I do?

Breastmilk can spoil, but with the right storage it keeps well. The key rule: milk left at room temperature (up to 25°C) should be used or refrigerated within 4 hours. In the fridge (4°C or below) it's good for 4 days; in a deep freezer it's safe for 6 months at -18°C.
Never refreeze thawed milk; once it reaches room temperature, use it within 2 hours or throw it away (bacteria from your baby's mouth can pass into leftover milk in a bottle, so discard it if not finished in 1–2 hours).
To thaw, hold the bottle under warm running water or place it in a bowl of warm water—never boil or microwave, as that damages nutrients. Keep storage containers clean and always cap tightly.
If you're still confused or have a special situation (storing milk while traveling to work, for example), feel free to ask more.
