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

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

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.

Love, love, love this bottle! My 3-month-old would gag and dribble milk with other bottles, but this one has made such a difference. The flow is much slower and easier for my baby to manage, so there's no more gagging or milk leaking from the sides of the mouth. My baby finishes feeds happier, seems more satisfied, and even has fewer spit-ups. I 100% recommend this bottle to any parent looking for a great feeding option!

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!!!

This is the best glass baby bottle I have tried. I breast fed my baby and he had no problem taking the nipple from this bottle. These have a little weight to them but the Dr Brown (glass) are more heavy and they broke from the top super fast. Thyseed does not leak. It’s so simple to clean and re-use. They need to make a 12oz glass with silicone cover for when you baby is older.

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!

Love this bottle. It's anti leak and expresses just like a breast would. Only thing I don't like is the small piece at the back. It can leak and get clogged and it's super small to clean but otherwise a great buy

I tried several different baby bottles before this one, but my baby didn’t seem to like any of them. I decided to give this bottle a try, and I’m so glad I did. The soft nipple was easy for my baby to latch onto, and the anti-colic design seems to help reduce gas during feedings. It’s also easy to clean and feels very well made. Feeding time has become much smoother since we switched. I’m very happy with this bottle and would definitely recommend it to other parents.

Muy bonitos, y excelente calidad 👌

Such a life saver
