Thyseed Anti-Colic Glass Baby Bottle for Breastfed Infants, Natural Feeding, Breast-Like Newborn Extra Slow Flow Nipple (0m+), 5 oz, 1 Pack

I am not someone who usually writes reviews, but I am genuinely so impressed with this bottle. I honestly did not want it to be any good because of the price. I knew if it made a difference, this was the solution, and it would be an expensive one. I am a single mom supporting both me and my baby, I don't make purchases lightly as I am on an extremely tight budget. Both fortunately and unfortunately, it was exactly what I was looking for and worth every penny. After buying the one, I went in and bought 3 more. We have an entire cabinet full of bottles, Dr. Browns, Parents Choice, Boon Nursh, Tommy Tippee. We probably have 20 bottles in our cabinet of all different brands. Since purchasing this bottle, it is the ONLY bottles we use. I am constantly washing and rotating just these 3 bottles. That's how much of a difference it made in our lives (and shows how easy they are to wash, only 3 parts!) I bought this bottle in desperation at 3:00 AM while trying to calm my refluxy 5 week old. He is combo fed. I both nurse and introduced bottles at 3 weeks of age. The bottles we were using before were a nightmare. Too many parts, nipple confusion, a weak latch, and worst of all, the flow was way too fast. They did not allow him to pause and take breaks naturally like he does when nursing, if he stopped sucking he was flooded with milk. Even when I stopped him to burp, it felt like he was being overwhelmed with milk. His reflux was awful and feeding was stressful for both of us. I bought this bottle as a last ditch attempt to make something work. I thought bottles just weren't going to work for us, but I am a single mom and was returning to work soon. I had to do something. Like I said, part of me honestly did not want it to make a difference because then I knew I would have to buy more. But it arrived, I used it, and it immediately helped. He latched onto it deeply, just like he does at the breast. The milk comes out of five tiny holes in the nipple, similar to a real breast, and no milk flows unless he is actively nursing. He can feed from the bottle the same way he nurses, without having to suck aggressively like with other bottles. The nipple is genuinely very soft and does feel almost like skin. It's weird, but it makes a difference. Within almost a day, this one bottle fixed our feeding issues. He can stop and take breaks without being overwhelmed by milk. Babies naturally nurse in a rhythm of suckle, suckle, breathe, repeat, and this bottle actually allows that. His latch is deeper and stronger, and the feeding feels much more natural. For someone who nurses and also uses bottles, this has been a total lifesaver. On top of that, the bottle itself is incredibly sturdy. I was nervous about the glass, but I have dropped it more than once and it has not broken. It only has three parts to wash, which makes a huge difference when you are exhausted. The design is simple, well thought out, and takes so much of the frustration out of bottle feeding. If money wasn't an issue, I would buy 10 more. All babies are different and do have different needs and preferences, but honestly if you are having feeding problems with the bottle but not the breast, I would recommend this bottle a thousand times.

Really love this anti colic bottle. It’s pretty well made. My baby had reflux, gas, and was very fussy. I tried so many anti colic bottles like all the popular brands and none helped him much. We switched to Thyseed and noticed a big difference. The best part is the very soft silicone nipple that feels natural. It has 3 holes at the tip and when baby latches on it mimics natural breast flow. It looks just like how you’d express breastmilk by hand. Pretty cool. The wide opening of the bottle makes it very easy to clean and scoop powder in. There’s a circle disc looking thing on the bottle that is the vent anti colic design. It’s easy to remove for wash & to place back on. This bottle doesn’t leak like others. I love it and my baby loves it… definitely more comfortable during feeds and less resistant to taking the bottle

This is the only bottle that truly helped my baby’s air-swallowing problem. After three months of trial and error, plus five different “anti-colic” systems, this one finally made a real difference. Feedings are calmer, burping is easier, and discomfort dropped immediately. I also really appreciate the glass design, seems pretty sturdy with thicker glass. Glass is naturally non-toxic, free from chemicals, and doesn’t absorb odors, residues, or bacteria over time. There’s no concern about microplastics, chemical leaching, or heat altering the material, which gives serious peace of mind when feeding an infant. It’s easy to clean, stays clear, and feels genuinely health-focused. The nipple shape works beautifully for a breastfed baby, and the flow feels natural rather than forced. My baby took to it right away and clearly prefers it over everything else we tried. While I agree the price is a little steep... If you’re dealing with colic, excess air intake, or just want a safer, cleaner feeding option, this bottle is *absolutely worth it*. I only wish I had found it sooner!!!

AMAZING bottle!!! Historically my exclusively breast fed babies have hated taking a bottle and would flat out refuse it, cry or gag. And with that, it made us as parents being able to go out for a date extremely impossible. I’ve always had a fear of them taking the bottle, and then refusing to breastfeed after as well. This bottle is AMAZING and SO worth the money. I’d pay more if I had to. Not only did our baby take the bottle so well (the first time minimal issues a few days before our date to prep) he had absolutely no issues latching and feeding when we came home!!!! Great quality product, love the glass, and FINALLY a bottle my breast fed baby will take. 1000/5 stars!!! - A mom of 5 exclusively breastfed babies!!

This bottle made our lives so much better! Feeding had become so stressful for me. I’m a new mom and my newborn stopped liking all of the Munchkin Bond bottles I bought. He was overwhelmed with milk when feeding even with a size 1 nipple. I was disappointed because I loved those bottles- they’re like Dr. Brown’s but food grade silicone instead of plastic for the valve. They weren’t cheap either. Anyway- I tried about 3 other bottles I had on hand that I’d gotten from sample boxes out of sheer desperation- he rejected all of them. It was a nightmare. He would go for the nipple, suckle, reject it, wail, arch his back, go for the nipple again and the cycle would continue. You could tell he was starving but couldn’t use the bottles I had. He seemed confused because I was breastfeeding also. This bottle was perfect for switching back and forth from breast to bottle. I bought 3 more and it’s the only ones we use now- he hates all the others. He’ll tolerate a small Philips Avent one I have so that might be a cheaper option that could work, but it’s plastic & I want glass or at least food grade silicone. I see that people think these bottles only have 3 parts but they really have 4 since you are supposed to take off the valve at the bottom of the glass bottle and wash it once in a while! It’s easy though. Especially if you have a bottle washer/sterilizer. I also think the bottles are so cute- retro and chunky. They look classy and high quality. His pediatrician even commented on them haha. Worth every penny and I don’t dread feeding him anymore. You just have to keep up with the nipple sizes. I just switched to the 3+ months ones and I’m getting ready to try the silicone version since daycare won’t accept glass bottles. Can’t say enough good things about this bottle. Even my mom was amazed. He stopped being colicky and fed happily. If all of the reviews sound like what you’re going through…Just buy one and try it out!

I love these bottles , great quality . My baby tends to prefer these bottles, it truly mimics a mother’s nipple with the 5 micro holes flow. Great for those breastfeeding mothers such as myself and it doesn’t leak , milk only comes out if he is feeding on it ! Plus glass is easier and more sanitary than plastic . I originally bought 2 to test it out but ended up loving it and bought another two ! I’ll end up buying the bigger ones later on !

I was about to give up on getting my daughter to take a bottle after trying literally every single popular bottle brand, and she kept rejecting them. I decided to give this one a try and I’m so happy I did! The ONLY bottle my exclusively breastfed baby will take. She happily drinks from this bottle and rejects everything else. The nipple is so soft, squishy, and similar to a real human breast. The anti-colic vent in the bottom is way easier to clean than the Dr. Brown green plastic insert. I love the heavy duty glass these are made of. I just ordered the transitional sippy cup and I can’t wait to try it out. Overall, extremely impressed and so happy with this brand! I can’t recommend enough.

My absolute favorite bottle ever. Pros: extremely small pin hole in the nipple so small it doesn't flow unless the child sucks. One way valve on bottom eliminates air intake. My child's fussiness from gas bubbles was dramatically reduced, far more than any other brand Very clean ingredients, high quality silicone, sturdy glass do important. Cons: the one way valve comes off the bottom and it's very very small and so easy to loose, I love the fact that it's easy to remove and clean but I've wasted a full bottle thinking I've put the bottom back only to have it leak all over the place The company could do easily give you at least one extra bottom valve it would cost them pennies but they chose not to which is really rotten, for 25 bucks you think they would provide extras, what's worse is they cost 6.99 for two and you have to pay a huge fee for shipping and they are only available on their website so terrible. But despite the selfishness of the company and the risk of losing a piece the size of a quarter it's still my favorite bottle ever because it prevents gas in my baby.
