Umm.. that's my entire question.  I know that an answer will not put 
an end to my son's gastrointestinal dramas but I would really like to 
know the answer anyway...

Why do newborn babies seem to 'smile' when they get wind?  That is, 
what is the physiological process behind this tricky reaction?

Thanks

Eve
