Have her try fenugreek or More milk. THey are supplements to help increase milk supply. Also have her see a lactation consultant/specialist. I read in "On becoming Babywise" that although many women think they do not make enough milk, only about 5% of women really don't make enough, and that there are things you can do to increase milk supply, including improving your breastfeeding technique. They have some tips in that book but I would really reccomend seeing a lactation specialist. If her baby is not latching on properly she might not be getting enough stimulation to produce enough milk. Also, I do not know what kind of pump she is using but that could effect it as well. She might try renting a hospital pump for one month, since they are far superior, to increase her supply. I never got engorged and I never feel let down either. I make a lot of milk in the morning hours but not a lot in the evening. People tell me that babies are just fussy inthe evenings, but I think its becasue she's hungry. She goes for a couple of hours between feedings during the day, but at night starting at about 6 or 7 she wants to eat almost every hour. Maybe thats normal, but I always feel so deflated in the evening, and I think she's just hungry. Last night we tried giving her a bottle that I had pumped earlier, when I seem to make more milk, and I nursed her on top of that. Happy Baby. I am going to try that mroe often. She slept seven hours in a row last night!! I'm a first time mom as well (my girl is 5 weeks old) so I don't have the most experience, but I hope she finds those ideas helpful.
good luck
