The majority of ACC child injury claims nationwide were for minor injuries. Soft tissue injuries, such as bruises, strains and sprains, led to around 152,600 claims, while lacerations, puncture wounds and stings resulted in around 98,100 claims. The next most common injury category was fractures and dislocations. Other injuries included dental injuries, burns, "foreign bodies" in eyes, and concussion.

That means talking to them about risks and being a good role model."
