– Parents watch eight month month old child play with a toy phone from a distance.
– Child slams the phone and breaks it.
– Parents recover most of it including a battery.
– The night is uneventful.
– In the morning they discovered 2 more discolored batteries – when the baby poops!

This child was very lucky that he also had a diarrhea and the batteries came out before they could cause any damage to his gut!
This was the perfect recipe for disaster – a toy with small parts in the hands on an infant. Not everyone ends up as lucky as this child!

As you can see the two swallowed batteries were quite discolored and almost rusty!
