Ok people, plain and simple.
Parent Buy stuffs
Some stuff is poisonous
Parent put stuffs away
Parent put poisonous stuffs out of reach of children
Plain and simple. Those who don't do the above...well, obviously they're not meant to be parents if they can't be careful for their children. My brother once got into the medic cabinet and ate shitload of stuff that was bad and ended up having his stomach pumped. Of course, my mom was smart enough to put them in another cabinet that was out of his reach but still within my reach
