There s no medical reason to warm up formula.
Baby formula milk room temperature.
Milk straight from the breast has a similar temperature.
It might be frustrating to see that your little one is not finishing their bottle.
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.
Others do so because it seems more relaxing for the baby that way.
However it will also happen quite frequently especially during their first weeks of life.
Some parents like to give their baby a bottle of warm formula because they believe that makes it seem more like breast milk.
It s fine to give your baby room temperature or even cold formula.
If your baby prefers warm formula place a filled bottle in a bowl of warm water and let it stand for a few minutes or warm the bottle under running water.
Warm the formula if needed.
After this time frame passes you should not feed it to your baby anymore.
The formula should feel lukewarm not hot.
And if preparing formula ahead of time keep refrigerated or in a cooler.
However if you give a baby formula made with cold tap water it could be more than 40 degrees fahrenheit colder than breast milk.
Use prepared infant formula within 2 hours of preparation and within one hour from when feeding begins.
Formula that s been prepared should be consumed or stored in the refrigerator within 1 hour.
Don t use formula that s been kept at room temperature for more than an hour and discard stored formula after 24 hours of preparing.
Prepared infant formula can spoil if it is left out at room temperature.
If it has been at room temperature for more than 1 hour throw it away.
Your baby may prefer it warm at room temperature or even chilled and all of those options are just fine.
As a general rule the bottle will last for 2 hours at room temperature untouched and unheated.
Tap water temperature varies depending on location and the time of year.
No matter how your baby likes her formula always follow the manufacturer s preparation instructions.
