What is the best way to clean my bottles?
All components are dishwasher safe, but we recommend hand washing in warm, soapy water for best results and a longer lifespan. To sterilize, you can use steam or boiling water (just keep your bottles from sitting on the bottom of the boiling pot).
How many bottles and nipples do I need?
Newborns can feed 8-12 times daily, so we typically recommend having six bottles and nipples on hand. From there, decide if you need more based on how much cleaning and sterilizing you do and your resulting comfort level.
How can I tell what flow rate I have?
On the underside of each nipple near the edge, directly opposite of the anti-colic valve, you’ll find a flow rate indicator etched into the silicone base. “S” for Slow Flow, “M” for Medium Flow, “F” for Fast Flow, and “X” for Flex Flow.
How do I know which flow rate my baby needs?
We have recommended age ranges for each nipple size, but every baby is different, and there’s no ‘right’ time to swap sizes. If your baby is taking too long to feed or falling asleep while feeding, it could be time to size up.
How do I convert my bottles into sippy cups?
The BuubiBottle SipKit by Quark is a toddler cup conversion kit designed exclusively for BuubiBottle. Each kit includes an ergonomic grip collar and an easy-to-clean, leak-proof 2-piece straw.

Best bottle ever bought
The packaging of the bottle looks great. Iâve bought multiple brands in the past and yet this is the best one so far. The bottle is made of great quality and it’s spill-proof! My baby latches on this bottle very easily , the feeding process was very smooth because of its anti-colic valve.
The BEST combo feeding bottle.
My daughter has been only breastfed since birth. Untill my doctor said she was in the 10th percentile and needed to gain some weight, which meant adding formula to her diet. We tried every bottle at every store near us, endless screaming. I felt so bad for my baby. Untill I tried these. She took it right away no hesitation. Like it was a breast. I couldnt be more greatful for this brand, bringing peace of mind to my family and helping my baby thrive.
Disappointing quality control
Have had good luck with the Quark brand through the first week of my newborn sonâs life. Such that we bought two extra sets of quark bottles to reduce the amount of cleaning between feeds that weâd have to do. Sadly all of the nipples in our set are faulty. They come with the slow flow nipple, but this may as well have been the no-flow nipple. Our poor baby has a tongue tie so we figured he was just slow to drink 40mls of formula because of that⦠how frustrating, irritating, and obnoxious to realize too late that it wasnât his fault, but Quarkâs poor nipple quality control that led to him exhausting himself for a single drop. Do a double check of your nipples ability to leak liquid so your child isnât burning calories trying to eat. Definitely makes me second guess going with this brand moving forward.Attached video shows how nonexistent the flow was
Good quality, plastic is sturdy, Baby seems ok with it!
Arrived on time, packaging came in a beautiful sealed box, the bottles felt like good quality with no plastic smell. Impressed with how thick the plastic is, it almost feels like glass. Tried it out and baby seems to have no complaints so far!
Works great but
These bottles were recommended by our lactation consultant for our breastfed baby. They work perfectly for the go between to givr me a break! This bottle set has daily use, including in our warmer. Which leads me to my one complaint. The sides of the bottle have water staining after 1 round in the warmer. They now are rough and not great looking. But otherwise the product works great. Not sure why these bottles are the only ones impacted by my warmer.
Deformed and ruined within a week
This bottle initially seemed great, but after just using it for a few days it became completely deformed. It happened with both bottles that came in the package. This must have happened during the sterilization. I contacted the company and they said they never heard of such a thing, but based on other reviews online I know that it is a known issue with these bottles.
My niece only takes this bottle
My niece do not take bottle right now, which is a big headache for my sister at the moment. So I purchased this one hoping that my niece will like it. This is now the only bottle she will accept, so it looks like weâll be ordering more!!!
Bottle
My breastfeed baby loved it hope she will continue using ıt
Excellent quality, dising and ergonomic. Most have for all moms that continue breastfeeding and need a transition.
We exclusively breastfed for a long time, but wanted to introduce a bottle just in case of emergency and I wasn’t able to be there. My baby is suspicious of the bottle – he definitely doesn’t love it, but he will begrudgingly take it if the real thing isn’t an option. He definitely doesn’t drink as much or as fast, but it gives me peace of mind having these on-hand knowing that if someone else needed to feed him they could!I didn’t love that these are plastic, but they’ve held up really well to washing with no visible scratches or cloudiness and I don’t worry about it shattering if it gets dropped or chucked!
4 stars because in a long term use it tends to deform because of warm water and hard to tighten lid.
I got these bottles a few months back for my granddaughter, and although my daughter was exclusively breastfeeding her, I knew that one day these would come in handy when she transitioned to pumping.My granddaughter is now 6 months old, and my daughter is trying to ween her off the boob and pumping more, so that she can return to work.Sheâs finally had the chance to use these BuubiBottle Mini Slow Flow Bottles, and she thinks they are really fabulous.The nipples are designed to be very similar to motherâs breasts and simulate breastfeeding; my granddaughter has no problem feeding from these well-made, excellent quality bottles.They are easy to clean, as they are dishwasher and sterilizer-safe; she actually cleans & sterilizes them in her Baby Breeza Superfast machine.She highly recommends these bottles!!
My son did so well with these bottles, better than any other kid we tried! They’re such a pretty color too, he points at them and specifically reaches for them over other bottles. They’ve held up very well with regular daily use too! I definitely think they’re a great value for the cost! Great quality, leak proof, excellent performance!
