8. Toilet
Yes, it sounds funny and almost unimaginable that your child would want to play IN the toilet, but there have been reports of both accidents and drowning deaths from children becoming lodged in commodes. Try and keep your bathroom door closed as often as possible to prevent toilet play time, and also invest in a few toilet locks. They are simple enough to remove for adult usage, but not so simple that your kids will unlock them.
