Caterpillars have spikes that they use as a defence mechanism to deter predators. The spikes are very painful if stood on. I talk about treating toddlers who have stood on caterpillars as well as treating children with gravel rash after falling off their bikes.

This podcast will teach you how to remove hundreds of spikes from the feet, and how to treat gravel rash with Duoderm, a favourite hydrocolloid dressing.
