[Relevance: Wrong Ways Storing Breast Milk ]

Do not Over Pump and Store

There are a lot of mums that go on a pumping spree. They pump and store ridiculous amounts of breast milk which lead to them not using up the milk. To prevent wastage of your breast milk, make sure you pump only what is needed by the baby for a particular time.

Know When To Bin Your Stored Milk

It is important you know when to get the stored milk out and dispose of them. Breast milk stored at room temperature can only last about four hours before they start to lose their taste or nutrients while milk kept in the fridge can only last up to four days. It is best for you not to think about the milk going to waste but rather dispose of them off immediately they pass these times.

Always Keep your Milk Cold

Always put your milk in the fridge immediately after pumping into the storage bags because, the more time it spends at room temperature, the more it loses its freshness.

Know When To Freeze

The only time it is necessary for you to freeze breast milk is when you know you are not going to use them under 24 hours.
