This teether is great for my two month old. Although he's not fully teething yet, he's already at the stage where he needs to suck on something constantly. Usually it is his hands he sucks on but now he likes to suck on the citrus teether. It has a lot of texture that he will be able to discover and it's small and light for his tiny hands. I wish I would have found this for my now 2 year old.
