Keep stairways properly illuminated. Use gates to prevent children from playing on stairs. Do not use accordion style gates. Children can get caught in this style of gate and get hurt. Use door knob locks to prevent children from opening doors to the basement, garage and other unsafe areas.
Larger openings permit children to place their head between the rails and get injured.
Install a plastic rail guard or rail net to prevent children from getting through the rails. Make sure hand-rails and banisters are secure. Be sure furniture is properly assembled. Always keep the side-rail up when the child is using the crib. Keep mobiles out of the reach of the baby.
