Tip on Storing Milk in the Freezer
Storing milk the conventional way in the freezer can be a space waster as it is bulky. Milk storing bags are designed to have the milk stand upright and when it freezes the bag expands. I have been freezing milk flat so that it saves space since you can stack them one on top of each other in the freezer.
I place frozen milk bricks in a larger zip loc bag (the medium size bags can hold about 15 milk bricks). Milk bricks take a lot less time to defrost. You need to make sure that the milk bag is sealed tightly and make sure to get all the bubbles out first.
Before I pour the milk into the bag, I write the date on the date tab first with a pen. Then I indicate how much milk there is (with a thicker marker on the measuring guide on the bag) because when you defrost, sometimes you need to do some math to get the amount of milk you need for the feeding(s). Then I number the bags in order. That is so I don’t have to rifle through the zip loc bag to find when the ‘next date’ is. If I used up number 5, I know that bag 6 is up next. The date is written for the purpose of expiration. If remembering the number is too much work, you can mark the next one with a post-it note or a coloured clip (see first photo, marker on the right with the green post-it).
When you defrost, place the frozen milk on a plate just in case it leaks so that it can catch the drips. If you notice the bag was ripped in the freezer, it’s better to throw it out.
I label everything clearly and indicate the volume of the milk. You will be glad you did if you are in a rush or if you are instructing someone else to defrost milk in your absence.
