Chris,
I would vote for dairy allergy.  Baby was on Enfamil 24 for 2 wks in hosp -
takes 2 wks for babe to be sensitized I think.  Symptoms started on way home
- makes sense. Does mom consume dairy or have family hx of allergy - she
should eliminate that.  I vote for Nutramigen (Mead Johnson) or
Alimentum(Ross) for the formula to use during transition to total human milk,
if possible.  They are the hydrolyzed, hypoallergenic formulas. They are
expensive.  I am not familiar with Neocare.  The baby may indeed have reflux,
but the reflux could very well be caused by a dairy allergy.  I vote for
football hold to keep baby upright and to keep baby upright after fdgs.  Some
peds use Maalox I think to soothe the irritated esophagus in the short-term;
many mothers report good results with this and there are some with flavorings
- of course  mom needs ped to prescribe what is appropriate for this baby -
just now reaching corrected age of 38 wks (full-term).
Mom should strive for increasing supply so baby can get off artificial milks.
Maybe the mom could take the reglan - it is used to increase supply. The iron
may be an irritant too, but I would mess with only one thing at a time,
especially since this was a premie and did not get the last few wks to lay
down iron stores.  Perhaps mom could change her prenatal vits if they contain
iron since she is now 6 wks postpartum and does she really need it?
Hope this is helpful,
