Never leave your toddler alone in a bathtub. Never leave your toddler on a high place like a changing table, sofa, or kitchen counter. Don't let anyone smoke around your toddler. Always keep crib rails up and the mattress at the lowest setting. Keep plastic bags, balloons, safety pins, and small objects such as coins and hard pieces of food away from your toddler.
Toddlers are curious.
Lock up your guns and bullets separately. Your toddler may wander away from you when you aren't looking. Watch your toddler carefully. Keep medicines, poisons, and sharp objects locked up. Use gates by stairs and review the Home Safety Checklist.
