In an ideal world, you'd have breast milk on hand whenever necessary and safely stored away whenever not necessary.
Unfortunately, that timeline doesn't always match up with the human body, which is where breast milk storage bags really come in handy.
Breast milk storage bags can keep your milk fresh, organised and leak-free - stored safely and securely, whether it’s in the fridge, freezer or on the go. Choose the right storage bag and you'll feel like Mum of the Year, whipping it out at the right moment. Choose the wrong bag and you'll feel fury like no other.
Choose bags that are made of food-grade, BPA-free plastic. BPA is a chemical that can leach into your milk and harm your baby’s health. Food-grade plastic, as its name suggests, is designed to prevent contamination and preserve the quality of your milk. Some bags are also pre-sterilised, which means they're ready to use and don’t need to be washed before filling. If you're short on time (which tends to come with the whole 'parenting' thing), this is a must.
Look also for bags that have a secure closure system. This can be a double zipper, a twist cap or a spout. A secure closure will prevent spills, leaks and air exposure, which can reduce the nutritional value of your milk. You also want to make sure that the bags are easy to open and pour, especially when you’re transferring the milk into a bottle.
Most bags can hold up to 150ml of milk, but some more and others less. Choose a size that matches your pumping output and your baby’s intake. You also want options that can lay flat or stand up, depending on how you plan to store them. Laying flat can save space and make thawing faster, while standing up can make pouring easier and prevent tipping.
