Dear Heather, It's semantics.  1/2 of all babies do spit up.  Now we are
calling spitting up reflux.  Makes it a medical dx. and can generate more
tests, meds etc.  Actually a baby only needs to be investigated for refux
if not gaining or having breathing problems from reflux.  I repeat happy,
gaining spitters are a laundry problem.  Also breastfeeding seems to have a
positive effect.  The spit doesn't smell bad or stain and mothers sort of
ignore it.  Re: vomiting.  I think there has been research that shows there
is less pyloric stenosis in BF babies.

 Babies spit.  It's a fact of baby life.  Sincerely, Pat in SNJ
