A trainer specialising in delivery of training for disabled children was told that they can no longer give children toilet roll centres to play with because of health and safety.
This myth runs and runs. School science organisations such as CLEAPSS, the Scottish Schools Education Research Centre along with the Association for Science Education are clear that as long as toilet roll centres and egg boxes look clean, there is no reason why they should not be used. Everyday living presents a similar microbiological risk. Perhaps more energy should be put into making sure children (and adults!) wash their hands properly after using the toilet.
