Hi, I think seeing the LC is important. She needs to find out what is ‘causing” the problem to know how to fix it. But as others have said, it would be unlikely for her not to be unable to breastfeed because she couldn’t make enough milk. What sort of pump does she have? All pumps are not created equal and for this job she needs to hire a medela symphony. And feed frequently, at least every 3 hours and plenty of skin to skin
