When you are exclusively breastfeeding, one of the things on your to-do list is to pump and store breast milk every day. You store the milk mostly in special plastic bags that are designed specifically for collecting and storing breast milk in the fridge or freezer.

The majority of nursing moms use the Kiinde Kozii twist pouches or bags.

They are popular because of their practicality and ease of usage (both in terms of feeding the infant and in terms of pumping into them).

These pouches can be a bit more costly than other options for storing breast milk. This leads some parents to consider recycling them multiple times. Nonetheless, should they be employed again?

The reusability of Kiinde twist pouches is an unimportant side issue; first, let’s examine what sets them apart.

Kiinde Twist pouches, what are they?

The Kiinde twist pouches are part of the Kiinde Twist system, which is designed to collect, store, and feed the baby.

They are loved by many breastfeeding moms because:

  • Pump into them

You can pump directly into the pouch using a compatible adaptor, depending on the type of pump you have.

Luckily, the pouches can lock onto most pumps, especially from the major manufacturers. However, the adapters for the pump are sold separately.

Moms who have used these pouches agree that it is much easier to pump milk directly into the bag than waste milk when transferring from the bottle into the bag, especially when traveling.

  • Easy to store

After pumping and collecting the milk, you can store the pouches in the fridge or freezer.

They are sturdy, so they can stand firmly without toppling over in the freezer. For more compact storage, you can lay them flat in the freezer and you will able be able to fit more pouches.

  • They have a feeding system.

When it comes to feeding, Kiinde twist bags differ from other breastmilk storage bags in that you do not have to transfer the milk into a bottle.

Simply warm the twist bags in a bottle warmer or in a bowl of hot water put the pouch into the Kiinde Squeeze feeding bottle and feed the baby.

This bottle is included in the starter kit, so you do not have to purchase it separately.

In addition, the squeezable bottle comes with an active latch nipple. If you prefer nipples from other brands, you can use the direct-pump adapters, which are included in the starter kit, to attach the nipple.

  • Do not leak

The twist pouches are thicker than the other milk storage bags; hence, they do not leak.

  • Fit in a bottle warmer

These pouches fit quite well in a bottle warmer such as the Kiinde Breast Milk Bottle Warmer.


  • Free of toxins and other chemicals

They are free of toxins. The pouches are made from a material that is free of BPA, Phthalates, and PVC. Moreover, they also come pre-sterilized and ready for use.

  • They come in different sizes.

They come in packs of 22, 40, 80, and 320, so you can buy more to avoid running out. In addition, they come in different volumes of 6 ounces and 8 ounces.

  • Grow with the baby

The Kiinde twist pouches grow with your baby. You can use them to feed pureed food once the baby is no longer breastfeeding. There is a Kiinde Foodii System that is designed to use the twist pouches so that you can use them to give your baby pureed food.

Are Kiinde twist pouches reusable?

I came across a certain forum for moms discussing whether or not these milk bags should be reused.

To my surprise, every comment from the nursing moms said that they do reuse the bags at least once. In addition, one parent went ahead to state that she reuses the bags about 5 times after washing and sterilizing them.

But what does the manufacturer say about reusing these pouches?

What the Manufacturer says

The manufacturer clearly states that the twist pouches are recyclable but not reusable (There is a big difference between recycling and reusing)

What does this mean?

This simply means that the pouches can only be used once and then discarded. They should not be washed, sterilized, or reused.

Remember that the pouches come pre-sterilized; hence, once you use them, they are no longer sterile. In addition, after the first use, there is a high chance of bacteria growing inside the pouch since it is nearly difficult to wash and dry them completely.

“The pouches are hard to clean so they might pose a health risk to an infant if reused,” says the manufacturer.

However, the pouches can be recycled with regular bottles. You can also go into single-stream recycling.

Can you reuse breast milk storage bags?

One important thing to note is that all breast milk storage bags and pouches are not reusable. So, they should not be reused.

If you would like to store milk in reusable containers, you should go for some of the most popular containers that are safe to reuse, like the Philips Avent storage cups and Lansinoh breastmilk storage bottles.
