Is it possible to refreeze the breast milk not warmed

Should the expressed breast milk remaining after feeding the baby be discarded immediately (as a mixture) or can it be stored and used at the next feeding?

There are no studies that would respond to thisquestion, but, in principle, you can leave the milk until the next feeding. Here the question is in the other, how to store it, because when a child begins to consume expressed breast milk, bacteria from his mouth penetrate into this milk. Freshly cut milk contains live cells that kill these bacteria. In one study, it was found that in the milk, which was standing in the refrigerator for 8 days, the level of bacteria was lower than in freshly bred.

Many mothers leave half-eaten milk in the refrigerator for more than 2 hours (sometimes for 24-48 hours) without problems, but whether this milk is safe for the baby depends on some factors.

  • In fresh breast milk, there are more enzymes forcontrol of bacteria than in chilled or frozen. Milk, which was frozen for a shorter period, has more antibacterial properties than milk, which was frozen for a longer period. Although in any breast milk the bacteria grow much more slowly than in the infant formula.
  • The purity of milk is also influenced by hygienedecanting: washing hands, cleaning the parts of the breast pump according to the manufacturer's instructions, washing containers for storage in hot soapy water. All these factors will affect the amount of bacteria in breast milk.
  • If your child is sick or his immunity is lowered,it will have fewer opportunities to resist the "normal" number of bacteria. In that case, you will need to follow stricter rules.

To preserve breast milk for furthersome mothers re-cool milk and others leave it at room temperature - no studies have been conducted on this topic, so we do not know if one of these methods is more preferable. But we know for sure that for any food, cooling slows the growth of bacteria.

Guidelines for storing breast milk are notcontain no warning against the re-heating of milk and many mothers use reheating without any problems. Many mothers use the smell or taste of breast milk to make sure it is fresh enough.
