I agree with both previous posters. Having a new baby changes everything and especially changes the way you are, not yourself anymore but a mother. It is hard, especially for those of us, who were used to being very independent, earning nice salaries and so on. But when you get a newborn on your hands, the only thing that becomes important is this tiny little being.
Yes, feeding every 2 hours is normal, and actually I remember that my dd was nursing even more often in first weeks. It is exhausting physically and emotionally, especially when you don't know how to handle your little bundle of joy. I remember that somewhere between 4th and 6 weeks, Anna wanted to nurse every hour in the afternoons and I just basically made a nest for us on our sofa and didn't stir from there till it was time for a bedtime for her. What helped was doing nothing but taking care of her, dh had to do everything else, and I MEAN IT.
I agree with GraceKellysmom, if she goes with a flow at the beginning, she won't have problems with a supply. I never had.
Good luck to her!
