Lisa,
I worked as a night shift postpartum staff nurse with a baby who did not want
to suck. The baby rooted AWAY FROM the breast and only with a great deal of
encouragement would nurse, resting frequently.  He was only a few hours old
when I began working with him.  His mother was quite young but extremely
patient, holding him skin to skin. talking to him, and gently encouraging him
to eat.   The baby had had a very rapid delivery and had a bruised face.  He
also had somewhat bluish arms and legs, not always a real problem in the
first few hours of life.    Every time I went to the nursery to report on how
baby was doing at breast, I mentioned my concern about the baby's unusual
behavior at the breast.  I thought perhaps he was just somewhat disorganized
from a traumatic birth.

When the physician arrived in the morning, he ordered capillary blood gasses.
 The baby was diagnosed with persistent pulmonary hypertension and was soon
in 90% oxygen.  He did well, but it was a reinforcement to me to look at the
whole baby and not just the feeding.

The baby you describe MUST be seen by a physician who will listen to what is
happening.  Have you called the physician yourself?  I would document
everything thoroughly now if you haven't already using a "late entry."
 (Better now than later.)  Be sure you have mom's permission to share
information, and call the physician expressing your concerns.   Bonnie Jones,
