Eskimo, my niece just brought her baby home from UCSF after a two month stay...he weighed two pounds, two ounces at birth and now he's up to 5 lbs 6 ounces and he's doing great.
After watching the anxiety of my niece and nephew in dealing with this I can understand what you and Mrs. Eskimo must be going through...all I can offer is my best wishes to you and my prayers to God for your baby's eventual homecoming.
