It's easy to say that having a new baby is exhausting, but you don't really understand what it's like until you've actually gone through it yourself. Besides the exhaustion and pain of those first few weeks there's guilt associated with almost everything you do, especially feeding issues.
The staff at the breastfeeding resource center are invaluable for a woman who is having problems. They are full of good advice and they really believe in it, just the right kind of encouragement for someone who's frustration is beginning to overwhelm her commitment.
It's also a good place to get advice on pumps, bras, pillows, and all the other peripheral things that can make life easier for an nursing mother. You can also rent industrial grade pumps, almost a necessity for someone having supply issues.
