The natural rubber latex feels so much softer than the silicone ones we tried before, and my daughter actually finishes her bottles now instead of fussing halfway through. Just remember these are nipples only, so you need to buy the rest of the bottle separately.

My baby took to these way easier than the silicone ones we tried before, and the latex feels soft enough that she doesn't fight it. I do notice the color varies a bit between the two nipples since it's natural rubber, but that doesn't bother me at all.
