If my baby doesn't drink the formula I prepared right away, how long can I keep it at room temperature?

If your baby doesn't drink the formula right away, you can keep it at room temperature for a maximum of 1 hour. Once that hour is up, you must throw away what's left — putting it in the fridge and reheating later isn't safe either.
After formula is prepared, the mixture of powder and water becomes an ideal environment for bacteria to multiply. Most pediatric organizations, including the WHO, have set this window at 1 hour (some previously said 2 hours), and the time gets even shorter if your room temperature is especially warm, like in summer.
The safe habit: prepare only what you need for one feeding, and make fresh when your baby gets hungry. If your baby already put the bottle in their mouth, the saliva has introduced bacteria — so don't save what's left.
