Because of new-age parenting approaches, including goals to allow children more autonomy, young children are riskier and get hurt more often. As the population grows, rates of injuries and accidents have increased. Toxic substances and swimming pools are much more likely to be present in homes today. Laws and policies around safety and other guidelines have led to improved safety precautions, and injuries have declined.
