So far this teether is doing pretty well. My baby is 3 months old and has been rejecting most of the things I've given him to chew on. This one has something over the rest, though, because when he's upset I ask him if he wants his Vulli and set it next to him. He puts his arm around it and pulls it close to him or rests his hand on it and starts to calm down, before going to sleep. As for the chewing, he chews on the little knobies on the head. This is a great teether because it's so light and he's too little to be able to hold things that aren't really thin and light, so this is easier on him.
