Ilene,
If this mom really needs an SNS, why can't WIC get one for her?  I keep them
on hand & provide them for a "regional" area of local WIC programs, including
my 2 counties.  I know some areas have better access to them, but this is a
clearly purchasable item.

Does mom have any insurance or Medicaid?  In this situation, they should
cover at least part of expenses.  Can you find a pump/SNS provider willing to
give the mom a break on price, or take what insurance/Mcd reimburses?  Or if
you can find a pump rental station that has a "grant" program through the
company?  That may at least cover it temporarily.  If you don't get results
through the local WIC Program, call the state & find out who's in charge of
BF.  It may take some phone calls & leg work, but you should be able to get
something for her.  What state are you from?
Good Luck!!!
