All containers should be sturdy, and clean. They should also be single used containers and are usually glass and plastic, although with the warnings regarding hard plastics, it may be safer to only use glass containers. Never store breast milk in plastic bags or bottle liners. Labelling: Make sure you label each container with the date and time that the milk was expressed. This will make it much easier when you are using it and will ensure that you do not use the breast milk after the expiration.Make sure you label each container with the date and time that the milk was expressed.

Each time you express, the milk should be placed in a new bottle or container. You should also never mixed any breast milk left in a bottle after feeding with a fresher bottle. Simply dispose of the breast milk since bacteria is pulled back into the bottle with each suck from the baby. Also, you should never mix breast milk and formula. Everything baby needs is in the breast milk and there should be no need to use formula. If you are concerned about supplementing, speak with your pediatrician first.

Storage Length: Breast milk can usually last for 24 to 48 hours in a refrigerator. After that time, you should dispose of it. If you freeze the breast milk in a freezer that is attached to the fridge, it can last for about 2 weeks to about 3 months with a good freezer, although I would stick with the lower numbers for safety reasons. If you store the breast milk in a deep freezer that is not attached to any fridge, you will find that the breast milk can last for 6 months.

Heating Stored Breast milk: When it comes to heating, the best method and really the only method you should use, is to heat it up in cup of warm (not hot) water. If the breast milk is frozen, place it in the fridge for about 24 hours before you use it.
