Key Takeaways. If your baby doesn't finish their bottle of breast milk, you can reuse it within two hours. However, due to the risk of bacterial contamination, you should throw it out if it's been longer than two hours.
If your baby did not finish the bottle, the leftover breast milk can still be used within 2 hours after the baby is finished feeding. After 2 hours, leftover breast milk should be thrown away. To avoid wasting unfed milk, consider storing, thawing, and warming milk in smaller amounts.
It is not safe to reuse breast milk that has been left out longer than 2 hours. Dispose of it if this is the case. Breast milk should never be re-refrigerated or re-frozen.
Feed your baby between longer intervals
In the beginning, he might've taken five naps a day and drank milk five times as well. But as the number of naps decrease, he'll also have fewer times to feed. If he isn't drinking milk, see if you can stretch the times between feedings so he's hungrier come the next one.
Per the CDC, the guideline that we should follow is: If your baby did not finish the bottle, the leftover breast milk can still be used within two hours after the baby is finished feeding. After 2 hours, leftover breast milk should be discarded.
There isn't any conclusive evidence on whether or not this is safe, but some experts (and lots of moms) say it's okay to stick an unfinished bottle back in the fridge to reheat and reuse at the next feeding. (If baby doesn't drink it all at the next feeding, toss it.)
Once the breast milk has been warmed, you can give it to your child immediately or put it back in the fridge for up to 24 hours. Warm breast milk shouldn't be left out at room temperature. It shouldn't be frozen again.
Newborns generally sleep for two to three hours before waking to eat, day and night. As they get older, babies are usually able to sleep for increasingly longer stretches of time at night without waking to eat. Between the age of 2 to 3 months old, healthy babies are often able to sleep for six hours without feeding.
Signs your baby isn't getting enough breastmilk
But there are a few signs baby may not be getting enough to eat to watch for: Baby is sluggish or sleeping longer than usual. This is especially something to watch for in newborns. Because they are so little, newborns need to eat every 2-4 hours.
Stress or distraction.
Overstimulation, delayed feedings or a long separation from you might cause fussiness and difficulty nursing. A strong reaction from you to being bitten during breastfeeding might have the same effect. Sometimes a baby is simply too distracted to breastfeed.
Breast milk can be stored in an insulated cooler with frozen ice packs for up to 24 hours when you are traveling. At your destination, use the milk right away, store it in the refrigerator, or freeze it.
Toss any bottles your baby doesn't finish within an hour and any bottles that sit out for more than two hours – and don't reheat formula that has been warmed before. You can prepare a day's worth of bottles in advance and store them in the fridge for up to 24 hours.
To answer this question, Dr. Madden refers to the ABM protocol for milk storage, which recommends tossing any remaining milk that has been at room temperature for more than one to two hours. "Leftover milk should also never be given to a premature infant due to their higher risk of developing infections," she advises.
Bottles should be cleaned after every feeding. If your baby does not finish drinking a bottle within 2 hours, throw away the unfinished formula. Germs can grow quickly if breast milk or formula is added to a partially used bottle, or if a used bottle is only rinsed, rather than cleaned.
Some people describe a “soapy” smell or taste in their milk after storage; others say it is a “metallic” or “fishy” or “rancid” odor. Some detect a “sour” or “spoiled” odor or taste. Accompanying these changes are concerns that the milk is no longer good for the baby.
Your body is always making milk. That means there's no need to wait for the supply to “replenish” between feedings. In fact, waiting a long time between feeding your baby can actually reduce your milk supply. That's because your body does an amazing job of producing the right amount of milk to keep your baby happy.
Not enough milk: Your baby may sleep to conserve energy if they are not getting enough food. They may also sleep longer that is good for them if they are apart from you.
If you're low on calories, it could affect your milk supply and energy level – both of which are not good for nursing moms. So typically for women who are breastfeeding, I do not advise intermittent fasting.
For babies aged 6 months to a year, night feeds may no longer be necessary and some babies will sleep for up to 12 hours at night. Teething discomfort or hunger may wake some babies during the night.
You may have some milk leak from your breasts, and your breasts may feel sore and swollen. This is called engorgement. It usually gets better after several days. Over time, your body will stop making milk if you don't breastfeed or pump.
A few moms might be able to go 10 to 12 hours between their longest stretch, while others can only go 3 to 4 hours. Full breasts make milk more slowly.
There is no published evidence to support that shaking actually damages breast milk when compared to swirling.
If baby doesn't finish a bottle, you can offer it again within two hours of the last feeding. Before giving baby the bottle, you can warm the milk up by placing the bottle (or milk storage bag) in a cup of warm water for a few minutes, or pop the bottle into a bottle warmer.
Again, to avoid this you want to make sure that warmed breast milk at room temperature is used within 2 hours while the cold milk in the fridge should be used within 24 hours.
