Third Week of Life

The last couple of days have been difficult.  She seems to be sleeping better at night, but the days have become more difficult.  She is not sleeping.  I feed, change her diaper, and she is then crying to be fed again within minutes.  It is back to back feeding with no break in between.  I would like to pump some reserve milk but since feedings have been around the clock, it has been impossible.  I don't know what to do.  I am wondering if she is just having a few days of fussiness, or if this is how it is going to be.  Some have suggested trying a pacifier, but I am afraid it might interfere with the breastfeeding. We will see if things calm down in the next couple of days.
