Can I Use Leftover Formula Milk?

No, throw away any leftover formula. There's a chance bacteria may have formed since the last feeding, which could make your baby sick.

How long can you keep a bottle of formula after baby drinks?

Use Quickly or Store Safely

Use prepared infant formula within 2 hours of preparation and within one hour from when feeding begins. If you do not start to use the prepared infant formula within 2 hours, immediately store the bottle in the fridge and use it within 24 hours.

Can I use leftover formula for next feeding?

Always throw away any formula left in a bottle after feeding your baby. Do not refrigerate the leftover formula to feed it to your baby later. Drinking from a bottle means bacteria from the baby's mouth gets into the formula in the bottle, where the bacteria can start growing.
