Something for a baby to chew on (8,4)
I believe the answer is:
teething ring
(Other definitions for teething ring that I've seen before include "Something for the very young to bite -- getting her in (anag)" , "Comforter for an infant to bite on" , "Thing bitten on by a baby" , "Chewed-upon item for an infant" , "Something of comfort to little babies?" .)
