When I was in the hospital I breastfed her for the first night and next day.
She was doing fine, latching on perfectly, and I could hear her swallowing and see it dripping from her mouth.
The next day I was at the hospital, she was latching on fine, but no swallowing, no sight of milk, no nothing. So the nurses helped me out a bit, but still nothing.
So that's why.
*EDIT* and now i'm home, introducing her to my breasts as much as possible. and still nothing.
