Nursing another child is not that unusual. There were wet nurses until a few years ago. My mother's best friend from nursing school gave birth to a very sick baby who needed emergency surgery when he was born. He needed to be fed after surgery, but his mother couldn't so my mother offered to nurse him. She was still nursing my sister at the time. The hospital decided to use formula instead so it never happened. My mother's friend to this day remembers my mother's offer as the nicest thing that anyone has ever done for her. I guess it's a generational thing. My sister and I thought that was gross, but my mother and her friend thought that it was perfectly normal.
The problem is this woman didn't get the mother's consent. I don't know if there is anything wrong with this woman or not, but she shouldn't have nursed the baby without the permission of the mother.
The baby is now a healthy (and handsome) young man.
