Is this part of why everyone is so anxious to hear of the baby's first bowel movement? I know it's a sign the plumbing works, but I am not sure I would have included "the plumbing is connected" under 'works'.
I always thought this was for two reasons: one as you say is to show the plumbing works, the other is because not passing the meconium (combination of stuff ingested while in the uterus) indicates other more serious conditions might exist
