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

Review: Pricey but so worth it for babies who suffer from gas, reflux, & fussiness! - 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
Review: An Absolute Life Changing 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.

## Features

- Anti-colic base vent for fewer bubbles and calmer feeds: Clinically studied and published in JAMA.¹ The base vent helps separate air from milk to reduce bubbles and swallowed air, supporting calmer feeds with less gas and less tummy discomfort.
- Steady, paced flow to help baby feed more comfortably: Multiple micro-openings in the nipple give your baby a smoother, more even flow of milk to help reduce gulping and frustration.
- Ultra-soft silicone for a more natural feel: Flexible, soft silicone moves as baby feeds to support natural tongue movement and a more familiar feeding experience, especially for babies transitioning from breast to bottle.
- Breast-like nipple shape to help baby latch more naturally: Wide base with realistic breast-shaped nipple encourages a deeper and easier latch, reducing stress for baby and parent when switching between breast and bottle.
- Premium, safety-tested materials: Made with high-quality liquid silicone from WACKER (Germany), premium PP from TotalEnergies (France), and food-grade borosilicate glass. BPA-free, odor-resistant, durable, and designed for everyday feeding confidence.
- 6 flow rates designed to grow with baby: Choose the flow that best matches your baby’s feeding stage and comfort level for a more relaxed feeding experience.
- Fewer parts, easier cleaning: Assembly and cleaning are faster and easier, thanks to a simplified design with fewer parts and a wide neck. Dishwasher-safe (top-rack only) components.

## Questions & Answers

**Q: Why do bottles come in glass and PPSU? How to choose?**
A: Both designs are identical, but glass heats milk faster while PPSU is lighter and nearly unbreakable – both are safer with heat than regular plastic bottles.

**Q: Why does milk leak when my baby sucks?**
A: Warm liquid can build up pressure inside the bottle, ausing mik to flow through the nipple even without sucking. If this happens, unscrew the cap to release

**Q: What’s borosilicate glass? Is it better?**
A: It’s extra-tough glass that handles sudden temperature changes better than everyday glass, so it’s less likely to crack.

**Q: What’s the warming base pad for?**
A: It seals the bottle base during warming to prevent leaks – just remember to remove it before feeding your baby.
