Great teether for little hands. Flexible and easy on little gums and mouths. The "nubs" my son didn't line until about 5 months old (he started teething at 3). I love the case and it fits in most all pockets of diaper bags (too wide for a cell phone pocket though). Think case as well so I tend to toss it in my purse w a diaper and travel pack of wipes for a quick trip to the store. I also attach this to rings so it doesn't go flying.
This is by far my baby's favorite teether! I love that the material is safe and the little nubbies desensitize his gums for when we introduce a toothbrush. He loves that it's easy for him to hold (started using it around 4-5 months old) and he can chew on the smooth or textured parts and get relief in all areas of his mouth. We love this teether and he uses it everyday! :-)
