I need a little information and encouragement.

Mom, late 20s, married,  with carpal tunnel.  Baby born  full term at 8
pounds, 4 ounces after epidural delivery.  Bili at 18 at 48 hrs.  Bili
dropping very slowly, about one point per day.  Very sleepy, non-latching
baby girl.  Mom still edematous at 10 days pp.

Mother very dependent on her mom (the maternal grandmother for everything).
 The grandmother takes complete care of the baby.  Mom seems resigned to the
situation but asked me if I thought the baby knows who her mother is.  Baby
is now sleeping with the grandmother.

I received a call from the hospital.  Both baby and mother tested positive
for alcohol on a tox screen.  The hospital did the screen because mom
reported past cocaine use.  Mom called later that day asking how much beer
she can drink and still breastfeed.  The child protective services case
worker has contacted the mother.

My questions:  How soon after birth are the tox screens usually done?  Could
this mother have been drinking alcohol during labor?  I know she could, but
how long would the alcohol persist in a newborn's body if the exposure was
during labor?  Since this baby hasn't latched, she didn't receive the alcohol
through the colostrum.  Could the bili be dropping so slowly because of
continued alcohol use?  This mother pumps just three times a day, getting
about 10 ounces each time.  Would the alcohol in refrigerated breastmilk
dissipate?

This baby is 11 days old.  She's latched and fed only twice.  She's being
bottle fed EBM.  The CPS case worker seems to think this is an isolated
incident with a non-controlled substance (alcohol, not something illegal.)
 The pediatrician isn't scheduled to see the baby for another 3 1/2 weeks.
 This baby continues to be sleepy (drunk?  hungover?) and not interested in
latching.  I'm concerned.

I'm documenting all calls very carefully.  It's the grandmother (an RN) who
calls.  The mom is comfortable with this.  When I've returned calls and
mother answered, she always wants me to talk to the grandmother.  The family
dynamics are very interesting.  The mother has only called once to ask me
about beer.  CPS and the doctors are already aware of the situation.

Any advice?  Info?
