The nipple is so soft that it goes inside. I had to stop feeding to pull it out again. 5-6 times during each feeding, until the baby got tired.

Very good Dr Brown bottles, these are the only ones I use, very high quality. The only downside of the large bottle is that it is not as convenient as the small one and it is a bit heavier, but what can you do!

The best baby bottle, after research I bought 4 glass Dr. Brown bottles and now that we are reaching 6 months I am still using them, the only thing you change is the nipple according to the months. We had very few colics but the feeding was mixed with more breastfeeding

Very good bottle. Good quality material and construction. For a newborn, get the large ones right away so you have them for later.

Very good bottle, the baby accepted it without problems. The only negative is that it is somewhat heavy and when you shake the bottle with the milk after using very hot water, it has a leak.

Overrated.. they leak milk and if the baby is going to have colic, it will have it, they don't do anything special!!!

Many parts, a lot of noise, without real benefit. We found the Nuk anticolic bottles convenient; he doesn't eat well from the Brown nipples, especially after the 3rd month. Of course, we changed to the 3-6 month nipples, but with the Nuk he ate better. Also, if you keep it for 1-2 years, you need to change 4 to 5 nipples since the nipples change every 3 months, while with a Nuk you will change 2. Finally, the lid has a very strong seal and doesn't open with one hand... and believe me, at 2 AM with the baby in your arms, the last thing you want is for the bottle not to open! We didn't buy it again; we have it in the cupboard.

There is no better bottle, all the others are just to say we have them! The only one that really doesn't swallow air

The caps are very tight, and if you close them, you break your nails trying to open them. Also, the nipples are very soft, resulting in them bending sometimes if the child grabs them greedily, and the milk spills everywhere. I am disappointed

Perhaps the best among the glass Nuk bottles and definitely better than the Chicco one we had tried initially. Very high-quality bottle

The best bottles on the market. Although it's a subjective matter, we were saved with these! Very good choice and they help a lot with colic!

Having tried other baby bottles, this one is light years ahead! Initially, we never had colic, I don't know if the bottle helps to such a great extent or if my daughter happened to be like that, but we never had colic! The materials are high quality, durable, and user-friendly! The nipples are like new and without many creases that could be dangerous for bacteria (compared to another well-known brand). We love them!

I don't change them with any other. There are no better ones!
To release the milk before shaking it, open the lid and turn it abruptly with the nipple down into the sink, shake normally to mix the milk, holding it upside down. You won't have any leaks!

Very good bottle. I am very satisfied. My child takes it easily, without getting air inside.

Very good but I only used it once in the beginning when it didn't latch on to one breast due to engorgement. Since then, it exclusively breastfeeds so I didn't need it

We used it from the 2nd week of birth and the baby accepted it very easily, it didn't have any colic at all. Despite frequent sterilization, the glass part of the bottle looks like it was bought today, while the plastic parts haven't worn out so much. It's easy to use, but requires some attention to the individual parts during washing. It works perfectly even without the anti-colic system now that my baby is 5.5 months old. It's also very durable, our glass bottle has fallen down and didn't get scratched at all!

For my baby, it is the best bottle. It reduces colic, he accepted it easily, and it doesn't release milk quickly. Now, every baby is different, so I don't know if it is effective for all.

The most convenient bottle I have tried.
I have 2 ... one of them leaks when I shake it to dissolve the powder.

Unfortunately, it loses a lot of milk, especially when you shake the milk during preparation when it is hot. I have the same thing in the small size and it doesn't lose...at least not in such quantity!

The bottle is useless, it leaks milk from the screw and if the cap gets stuck, you need to have strong arms to open it...
We bought 4 bottles and unfortunately now we have to buy more.
