I recently was working with a mother of an infant who had this same problem
beginning at day 3.   He would nurse well and frequently with no problem, have
appropriate numbers of wet diapers, seem satisfied but have no  BM.   BM's
were late turning appropriate color also.  The infant had no problem with
jaundice.   I started getting  very nervous about this.  I spoke to a friend
who is a Pediatric Nurse Practitioner and she told me to have the mother
stimulate the rectum gently with a q-tip or rectal thermometer.  Presto!
LARGE BM within the hour.  But next day we were back to the same problem.  I
then insisted that she take the infant to the MD.  The MD stated that this
infant had the tightest rectum she had ever encountered and referred to
specialist.  Specialist concurred that rectum was indeed very tight.   The
infant should outgrow this by 4-6 months but meanwhile may be irritable at
times.  Mother was instructed to continue above mentioned stimulation two
times per day as needed.  Five weeks later the infant is now stooling on own
and stimulation is not currently needed.  MD (Pediatric Gastroenterologist)
stated "It's a good thing he is breastfed, we would have really had some
problems with formula feeds.  And don't rush into that cereal thing either."
I was very impressed with the doctor's attitude and that he told the mother
this.  We don't hear this very often in our area.
