Nursery rhyme characters form a new first aid campaign from St John Ambulance.

The initiative, with a musical twist, aims to teach people what to do if a baby stops breathing.

It comes after research suggests this is the first aid emergency parents are most worried about, but only one in four parents know what to do.

To tie in with the campaign launch, the charity is offering special baby first aid courses to parents in Bramford on February 3 from 9.30am-12.30pm, February 29 9am-12pm, and March 12 from 9.30am-12.30pm.

There are also sessions in Chelmsford on February 1 from 9am-noon, and on February 18 and March 19 from 9.30am-12.30pm.
