Just wanted to post my experience.  15 and 12 years ago when my last two
children were born, we left the hospital withing 3 hours of birth because they
were both born in the evening and the hospital would not "allow" me to room in
with them overnight.  After much communication with them, including letters
from both my ped and ob, they said their insurance would not permit them to
"allow" it.  Fortunately, I had two supportive Drs who had confidence in my
skills and respect for my wishes and they both released us to go home that
soon.  That was how I handled it.  Some say that you can just tell the staff
when they come to get baby, that baby is not done nursing and thus keep it all
night.  I didn't choose to take the chance.  I am amazed that any hospital is
still doing this at this point in time, though I worked recently at a hospital
that instructs patients that baby must go to nursery if there will noone awake
at night to watch it!  (Never figured out who they thought was going to stay
awake all night the next night -at home- and watch baby.  Or the night after
that.  Or the night after that!  and so on.  But at least, it was permissable,
if conditions were right, to keep baby all night.
 I don't really have any further solutions than ones I've seen mentioned here,
but I always think you can get further with research in hand and there are
several articles out there citing these.  Moms should be encouraged to take a
proactive stand, write letters, refuse to let baby be taken to nursery (I
didn't want to fight staff, took "easy way" out) cite the patient bill of
rights.  Patients DO have rights!  Parents also have rights.  I love Dr Jack's
viewpoint:  "you prove to me that this separation is better, show me the
research.  Then we'll talk."
