Growing babies need larger dosages of milk, sometimes even more than anticipated. So, this becomes a terrible situation for many parents and all they need is a quick solution to this problem.

Since most bags store smaller quantities (4 to 6 oz.) and are only enough for a short period of 24 hours, most moms choose to buy another bag to meet these needs. In such a case, you need a larger bag rather than two mini ones. An 8 oz. bag is more than enough to solve this problem of quantity for you.

Unimom Breastmilk Storage Bag is a great item in terms of  Value For Money as this quantity doesn’t come with a compromise on quality. Surprisingly, despite being this large, it is accurately leak-proof and lead & phthalate-free.

Breast Milk Storage Guidelines

Before you choose the breastmilk storage bag for you, it’s important to keep these tips in mind:

  • Only opt for a food-grade plastic breastmilk storage bag or specifically designed glass containers to store your breast milk.
  • Pick a health-safe bag that is not made of toxic plastic and is BPA Free. Plus, a tamper-resistant seal ensures that the bag is unused and fresh to use.
  • Consider if this bag can hold itself in cold environments as after thawing your breast milk in it, you need to keep it in a refrigerator for at least one day.
  • You should have a fair idea about the milk needs of your baby. For example, a two-week or younger baby demands two to three ounces of milk per bag, older babies need four to five ounces of milk per bag, etc.
  • You should remember that warmer milk has a shorter lifespan so try to freeze any milk left-over after feeding your baby. Infants younger than 3 months, need to be fed on warmer milk, so this milk has to be defreezed and warmed again to feed them.
  • For 4-months old babies, slightly cooled milk can also work. But not before that, at any cost.


No matter how effective your breast cream or maternity bra is, milk spills and leakages are bound to happen and bother you. Milk storage bags can be a good resource here. Think carefully and pick the best breast milk storage bags for you.

If you’re looking to save time, a bag with a pumping feature will allow you to directly get the milk into it, rather than having to thaw it into a bottle first. Some of them hold a lot of milk, which is good if your baby is not too young.

I remember stressing my bag once, milk sprout out of it like a fountain. It happened to me because it didn’t have a sturdy double zipper seal on its top.  Properly made bags can keep the potential spills and leakages minimal.  So good luck with your bag!
