When my son David was born, the stream of advice that came from well-meaning friends and strangers overwhelmed me. At three months, David was still waking once, sometimes twice, a night to nurse. When I talked about this, I noticed looks from experienced mothers that suggested I was doing something wrong. Then, all the suggestions designed to help David sleep through the night came flooding in. When a child is born your life changes and you no longer sleep in large blocks of time, but rather in snippets here and there.
Nursing is obviously best for the baby and is supposed to be very relaxing for the mother.
I have to say that during the daytime, I just don't experience this. During the day, we face a multitude of distractions, and nursing sometimes seems like one more in a long list of tasks to accomplish. There is always something else that needs to be done or somewhere to go, if only this child would just hurry up and finish. In the middle of the night, something magical happens. These distractions just melt away.
