This is such a great teether. I may be a little biased since it’s shaped like a donut, but we won’t focus on that for long! Haha Seriously though, this teether is awesome! The shape of it makes it so, so easy for my daughter to hold. It also is both firm and ever so flexible so it stays in place just so, as she holds it in her mouth. The back side of the donut has teeny little nubs on it that also helps soothe. And lastly, but definitely not least it is BPA free and made of food grade silicone. Now that’s something that this mama can get down with!
