Tell her not to get discouraged, it took me 6 weeks to get my DS to latch. Here's a post I put up about it: http://forum.baby-gaga.com/about2373981.html
Contact your local La Leche League or see if your health insurance covers seeing a Lactation Consultant. Don't try to force baby on if they are resisting and crying and pulling away.
Good luck to her, and it's very nice of you to post on her behalf.
Also, check out some videos on YouTube or DVDs at your local library for more tips.
