This brought back memories of some celebrity/sports person who's daughter was playing by his treadmill and got her necklace caught on it. Somehow it turned on and she choked to death.
Necklaces shouldn't even be worn during play time....snag on stuff all the time.
I can't imagine letting an infant wear anything around their neck. A toddler either.
You do realize unless they are strung together with some sort of steel that is impervious to breaking that any small child will automatically put pieces of that into their mouth in an instant should it break?
Who in the world thought of something like that? How irresponsible! Kids choke to death on stuff like this. If mom isn't holding the baby in her lap completely focusing on that child then that child should not have any sort of access to a teething implement at all. They break/wear down and fall apart.
