My baby is 2.5 months old, I am breastfeeding, and this particular pacifier is the only one she accepted immediately. It hasn't caused nipple confusion and has made things much easier for me.

P.S. I started using it after 50 days, once my breastfeeding was established and after my pediatrician advised me that I could start using a pacifier.

very good (at least our little one only wants these pacifiers), but very expensive (for me), 4-5 euros each

I had high expectations because I had read reviews and watched videos stating that it is the most suitable pacifier for breastfeeding babies, but unfortunately, my baby had a different opinion. He doesn't want this specific pacifier at all. He liked one of the free samples from the maternity ward.

update.
My baby is now 6 months old and has started to love this pacifier and uses it as a teether. I have also added a meal in an Avent bottle during the day, and the pacifiers seem similar to him.

I did not use it at all. I bought it exclusively for a breastfeeding baby, but he did not want it at all! On the contrary, he accepted the ultra light one from the same company with a little effort at first and then he wouldn't let it go. Comparing the two pacifiers, I highly recommend the ultra light one!

The baby accepted it immediately. Before, we had pacifiers with silicone and a teddy bear design from a well-known company, but it kept falling out due to its weight. These are very lightweight!!!

It was accepted directly exclusively for breastfeeding babies, it did not create confusion of nipples and also does not cause irritation to the mouth, it is ventilated. However, it falls off very easily even now at 3 months, it is probably heavy. Another negative is that it does not have a handle to hold it, it has a strange shape

It is not for 0 months, let alone 5-6. The nipple is quite large in the front and it is inconvenient that it does not have a handle to hold onto. The baby kept choking when I put it in her mouth and when she managed to hold onto it, it would slip out because it was slippery from her saliva. Of course, I do believe that it resembles the nipple of the breast, which is why I got it, in order to stop breastfeeding because I didn't have milk and she had developed a habit of using it to calm down. Overall, we tried every brand of pacifier available and whatever strange ones I could find, which is why I also got this specific one. In the end, we ended up with another classic timeless brand
