Just pondering this. A boy in my sons class (year 5) swallowed a pen lid during a lesson today. Apparently he began choking and clutching his throat, then calmed down and said "oh it's ok, I've swallowed it". It happened late morning and his mum was called immediately, but said she couldn't come for him until the end of the school day which she did and took him off to A&E to get checked out.
I don't know her personal circumstances but my first reaction was that I would've been there like a shot, leaving work immediately if need be. However if he'd swallowed the lid and was ok, was there any harm done in waiting?
Just made me think. What would you have done??
