One feature I especially like about this teether is the hand shape. The fingers are the perfect size for baby to stick in his mouth, after all doesn't he do that all the time with his own? Each finger has a different raised design that helps to massage and stimulate the gums. The lower portion of the ring can also be used as a teether and is a lot firmer than the fingers. Mr. F even likes to angle the fingers into his mouth to reach the back gums (a feature not many teethers have).
The Nuby Softees Super Soft Teether even comes with a great carrying case that completely protects it; however, be aware that there are no holes for ventilation and that if you put the teether away damp mold could grow!
This teether is great for any age baby, and especially those that like firm teethers. One disadvantage is that is VERY hard to find! I found ours at a local discount store, but there are few out there online.
