Think like a baby
Crawling, toddling, or walking - if they can get into it, they will.
Anything electrical, poisons, drugs, cosmetics
, paints, breakable stuff, sharp edges - you name it; they'll find it. And, they'll figure out how to get into it or get hurt by it. Get down on hands & knees (or lower) and look from their viewpoint. Remember: prevention beats treatment!
