It took less than a minute for my 18-month-old sister to climb up on top of the kitchen counter-top and reach for a pill bottle that sat on the kitchen windowsill.The iron pills looked like M&Ms and she somehow popped open the child-proof cap.We still have no idea how many she actually ingested.My mother had been on the phone, back in the 1980s when we didn’t have cellphones and talking on the landline meant being tethered to the wall.
