The failure of a popular brand of baby dummy in Australia has sparked safety fears on both sides of the Tasman.

A baby boy choked on a Happy Baby brand dummy after the teat came off.

The company has not recalled the dummies; instead it has asked for the broken one to be returned for tests.

It has also warned customers not to over-sterilise their dummies, which it says will cause them to deteriorate faster than normal.
