Natural Start Glass Baby Bottle, Cup or Jar Set, 9oz, 3-in-1 Set for Babies with Slow Flow Breast-Like for a Natural Latch and Leak-Proof Travel Food Jar Lids

Great bottles, but you have to tighten them exactly or they leak. Once you get the hang of it, they are perfect. Shame can buy just replacement bottle not lid as dropped and broke one already. They are perfect as the baby can grown into them and have lids to store solids later.

Love that these are glass so they hold up longer than the plastic bottles. Design is easy to read and it's super easy to clean because there aren't a ton of pieces. It's heavier than the plastic bottles but it's worth the trade and baby doesn't seem to have an issue holding the bottle. Overall I feel safe using them. They aren't fragile, but they are not completely shatterproof, so if they get thrown down on the concrete they will break (ask me how I know).

I love these bottles! It's nice to not have to worry about micro-plastics. My baby prefers the boob, but he also doesn't mine these. Good quality, durable bottles.

I do not know why I was so skeptical of using glass bottles. I think maybe I thought they'd be too heavy? These are not. These are perfectly light weight, yet durable design. No leaks. They heat up quicker than plastic and silicone, without any fat loss due to sticking/film which happens mostly on plastic, somewhat on silicone. Most nutrients are in the fat, so losing that layer of fat means losing some of the best part of milk. And our mama milk is NOT as fatty as you think... every bit counts. Even with that big looking layer after it settles. Its not as much as you think!!!! These solve that entire concern. No nutrient loss, more rounded heating so also less nutrient loss during heating process. They heat up SO quick, severely reducing fuss time waiting for a bottle. 10/10 I will never bother with my other bottles again unless one of these busts (bound to happen to at least ONE! Theyre glass afterall.... ) Also I love that they come with both the grippy lid and the cup adapter lid... not sure why since the nipple can go in either. But its kinda neat? Maybe just a way to up the price point? These do 100% fit the NUK natural nipples, the opaque silicone ones that mimic the nipple. And those nipples are ngl far better than tommee tippee. The tt nipples bend around, my littles have a hard time trying to hold the bottle with those. And then they get spillage and spit up. With the nuk nipples, all issues gone. So I really love these bottles and that they fit the world's best bottle nipple!

They work as intended and look sturdy. Hoping to get good life out of them. They are a little heavy for the little ones to hold by themselves but that is expected of good quality glass bottles. The design is great too.
