Electric outlet covers
These keep kids from being electrocuted.
Power strip covers and cord wrap
For the same reason you buy electric outlet covers, you need to buy a simple power strip cover. You can also help keep kids from unplugging cords or choking themselves by wrapping cords in a cord shortener.
Toilet seat safety lock
Even if yours are toilet trained children, keep them out of the toilet when they aren’t using it. They could contact diseases, fall in or off when they want to do it themselves.
If you keep cleaners, medications, scissors, or other dangerous items in the bathroom cabinets, latch the cabinets to keep out little fingers.
The stove is another potential source of burns. Install an oven lock and stove knob covers. Check the temperature of the oven exterior, and keep the child away from the stove.
Put small safety gates at the top and bottom of stairs and at the entrance to the kitchen, garage or other off-limits area.
Children can fall out a window that is open only four inches. I insist on fresh air, so I prefer mesh window guards to window locks.
