Can I prepare formula ahead of time?
Although it’s not recommended, you can prepare organic formula ahead of time if you refrigerate it. Prepared formula put in the refrigerator should be used within 24 hours. Prepared formula left out at room temperature for more than an hour should be thrown away.
Prepared formula can contain germs that grow and multiply. These germs can cause a serious food borne illness, which can be life threatening for an infant.
