Is she nursing him or not? That might affect whether or not she can try my answer...
A little over a year ago, my husband basically lost his job, we couldn't afford rent so we started moving into my in-law's basement, AND I was having a miscarriage! None the less, my doctor said I was suffering from a very understandable case of "situational depression"!! She tried me on antidepressant (Effrexor XR) but I seem to be allergic to it- I got severe headaches and insomnia. Since my depression wasn't too bad, she then recommended I take some OTC St. John's Wort. Maybe that would be an idea for your friend, too? (as long as she's not nursing, that is!)
