What are reasons babies pass meconium in utero? is being postdates the only reason?

Meconium: Meconium is the same thing as stool. It is that the baby has passed stool or had a bowel movement. There are numerous reasons for this and almost all of them are not in any way a sign of a problem.

Varies: Pre-birth passage of meconium is generally viewed as a nonspecific sign of fetal stress. Post maturity can lead to poor placental blood exchange.A placenta that is marginal prior to labor may trigger this when contractions start, or of if moms blood pressure gets low.A knot in the cord or cord wrap around the neck may also set this off. Close monitoring may indicate the need for a c-section.
