"A baby who still smiles and laughs can't be seriously ill"

[emkana]

I read this in a book, also had a doctor telling me this, and sort of believe it myself.
But was wondering if anybody had any evidence to the contrary?

Sorry, double-posted this thread! Please ignore this one!

ds has been smiling and laughing today with horrid diarrohoea(sorry cant spell it)

Depends what counts as seriously ill... DD had a broken arm and was smiling and laughing (not quite 2 yrs)
