Question: Why is it important for educators and other staff to understand how trauma can affect a child's behaviour? Select the correct answer. Trauma only affects behaviour at home, not at the service. Trauma can change how safe a child feels, so understanding this helps educators and staff respond with care instead of calling it 'misbehaviour'. Trauma looks the same in every child, so one approach works for everyone. Children should behave the same as everyone else once they are at the service. Need Assignment Help?
