@roger,
Funny story - when my kids were young.. the older one said her younger sister put a toy in her mouth and she swallowed it. Some of those small things that you used to get on those bratz dolls (that I detested) - earrings or something like that.
In a panic, I call the doctor - they re-assured me that the items sold for children in US stores are all non-toxic so as long as she didn't choke, she would be fine and I should see her passing it (if you know what I mean).
Afterwards, she tells me she hadn't swallowed anything and had no reason for the lie. Thank goodness I never went to the emergency room or doctor's office.
Why do young kids make up such odd things?
