Electrical outlets can be dangerous for curious children. Install child-proof covers on all home outlets to prevent fingers and items from entering.
Toddlers love climbing stairs, which may be fun if supervised. Stair gates that fit properly will prevent them from falling down the stairs when you're not looking.
A gate at the top of the steps is obvious, but protect the bottom also. A toddler can be hurt on stairs, so make sure neither end is accessible.
Many seemingly innocent objects can injure newborns and toddlers. Install kid locks on cabinets, cupboards, refrigerators, and other appliances for safety.
Babies and toddlers love picking up and eating things. Marbles can choke, so pick them up and put them away.
Even when off, an iron is dangerous. Recent use will keep it hot, and the cable can strangle.
Jewelry should also be out of reach of children. Put necklaces, earrings, and other accessories in a secured drawer or box.
