I feel sorry for the little tike
I agree, contact a local La Leche League group about this. I don't think any hospital in the US is allowed to refuse breastmilk to a newborn (unless they have a disorder or disease where they can't have breastmilk).
In the meantime, have your friend pump, pump, pump! That way, her supply will be constant, for when she is allowed to take her baby home. A hospital-grade pump will help with this (though I have heard of some people using the Medela Pump In Style Advanced pump to maintain a milk supply). Also, have her massage her breasts before each pumping, so it will reduce the risk of plugged ducts. The pumped milk can be given in either a bottle, special feeding spoon or cup, or even an NG tube.
If this doesn't work, then I'd have a lawer in that NICU right away. Or even the local news station. Just because other parents are squeamish of a mom breastfeeding her newborn is no excuse to deny a mom's right to breastfeed!
