A clear silicone adapter that fits over a MAM style dummy that can be attached to my dummy bibs. 

Check out the range of dummy bibs you can use these on. You wont need one of these adapters if you have a ring style of dummy (i.e. Tommee Tippee) as dummy bits will attach irectly to the ring.

A dummy bib is a teething bib with an extra bit attached to clip your dummy to.

No need for an extra dummy chain holder.
