I highly recommend Bubka Breast Milk Bags. I also have a few of another brand and Bubka Bags are so much better, especially with having a tighter seal. I really resonate with them being reusable and have been super handy with storing my extra milk supply. I love that you can write on them with a whiteboard marker too!
Convenient and handy. Love that it is reusable. However, wish there was a better way to label the bags.
I’m SO glad I chose to purchase from this brand - customer service has been fantastic (prompt and polite). The storage bags are of great quality - haven’t had any leakages and they don’t take up much room in the fridge! The lid fits very securely - easy to take off if you do it slowly.
I’ve always hated using the disposable breast milk bags as they’re so wasteful - one pump worth and seal and too hard to refill. Finally a sustainable option!!!!!! These silicone bags are really user friendly with a good wide base that keeps the bag upright for easy spill free filling. The lid is tight and leakproof but quite easy to remove - just need to do it slowly.
These are great! Easy to use and store. Seal really well and don’t take up much space in the freezer at all - so much better than disposable ones and way more eco friendly which is always a win in my book! Also fit perfectly in my steriliser - bonus! Highly recommend
Let customers speak for us
from 239 reviewsI've really struggled with pumping in the past. I've found other pumps painful and overwhelming to set up and clean. The bubka pump allows me to multitask whilst pumping so it feels like less of a chore.
My main tips would be to make sure the breast plate is locked in so there's so leakage and to find the right suction setting, high suction doesn't necessarily provide the best output!

Fabulous
I was initially nervous about the pumping process, but from the moment I used my Babka pump all my worries disappeared! It’s so easy to use, and I love that I don’t have to sit and hold it, which saves so much time. Instead, I can go about my day with the pump discreetly in my bra. I’ve worn it while doing housework, in the car, and even at the footy! The Babka team has also been amazing! They have provided the most helpful and responsive customer service I’ve ever experienced!
I highly recommend this pump for anyone who is looking to buy one!
Such a great, easy to use pump.
I've been wanting to buy this pump for a while. But I kept holding off and i don't know why because honestly the pro 2 pump is outstanding! Very efficient, comfortable (especially getting the choice of the different flange sizes) and you can pump at your own pace with all the different settings to choose from. Thankyou bubka for creating such a beautiful product for all the mums out there 💖
Just received our breast pumps in the mail as well as the wipes and free freezer bag. Put them to use straight away and I can’t believe how well they work! I’m not stuck on the couch anymore and I can’t believe how much more milk I was able to express with these pumps! I am so glad I purchased these and will definitely be recommending these to all my friends! All the parts are such high quality and I have a range of flanges to choose from instead of the stock standards like the other pumps. Plus I love being able to support an Australian business.
Everything Bubka has been super supportive during my breastfeeding journey. From on the go Pumps, on the go cleaning, soothers for sore nipples and even their custome service. When I didn't receive my back ordered wipes, I sent an email during their time off over the christmas/new year break, expecting to not get a response until they were back. However, they responded super quick and had my products in the mail straight away. Super happy!
Took these on an overseas trip recently and I don’t even know where to begin…These wipes were literally the MVP of the trip!!
Thought I would need them just for my Bubka, and bubs bottles, but instead I used them to wipe down all my toddlers toys, plates, snack containers…and the thousand other things I took to keep them occupied.
Love that they are food safe, so easy to use and leave no sticky residue or funny taste...
My only regret was that I only took one pack!
Efficient, plenty of functionality, quick charging, long battery life and allows freedom to move around and get jobs done! Truly an amazing breast pump for the modern working parent!
The Bubka has allowed me to continue my breastfeeding journey and I am so grateful! It's easy to use, simple to clean, excellent quality and most importantly effective. Highly recommend this pump!
Being a first time mum it’s overwhelming what’s available out there for pumping and breastfeeding. I purchased a pump from a brand used in the hospital and when I left the hospital I was wondering why the pump didn’t feel right. I didn’t realise there was such a thing as flange sizes… I stumbled on Bubka through a google search to try and find a flange size to fit the pump I had. Bubka had a wearable pump that is sold with multiple flange sizes! I purchased immediately and have loved the product since. It is discreet and easy to clean. When my pump wasn’t running 100%, I contacted the Bubka team and was so glad they were able to assist straight away. I cannot fault their customer service. Alicia was not only so helpful but also took time to have a chat after about my experiences as a mum. Would recommend this product and company.
Thanks so much for creating a product that makes cleaning your pumps so easy when you’re not home. I don’t have to worry about rushing home to clean my pump as I’ve got the wipes to make it so easy. Also amazing to clean the kids toys they’ve dropped when we’re out. I love the fact they’re bamboo too!
As a nurse we use silver for a lot of healing methods, and it is so amazing these soothers exist for sore nips when breastfeeding. They heal your sore nipples within hours. So easy to just pop in your bra, you don’t even realise they’re there! Can’t wait to buy more to add to baby shower gifts :)
I had a client who struggled with the suction power of her current pump. Her milk supply was dropping, so I suggested she tried my BUBKA. What a difference this little hands free pump made to her breastfeeding journey. She felt so much more confident with pumping and her supply. To top it off, she felt so free not being attached to cords on the couch. What a phenomenal product helping create a positive impact to women’s breastfeeding journeys. Everyone who’s pumping needs a BUBKA in their life!
