Probably the other thing that parents wouldn’t think of as being highly toxic is iron tablets, and iron tablets can commonly be prescribed to mothers after they’ve had a baby.  And I have seen a little girl who managed to swallow 20 iron tablets and when we X-rayed her, they were all stacked up in her oesophagus. They cause both a caustic injury to the oesophagus and then they cause a systemic toxicity as you start to absorb the iron tablets.  So that little girl managed to swallow 20.
