I hired a medela symphony double pump and loved it...I didn't have a lot of milk and it was the only pump that got anything out.
But I agree with the others that you will only get colostrum until your milk comes in after bub is born....hand expressing is just as efficient for colostrum as the pump.
I have had friends that have done the same and the colostrum has been enough for bub for the first few days as it is so rich.
You may only get 1-.5ml each express but that is good.
Good luck...I hope bub can avoid the NICU.
