Meconium blocks the neonatal airways. Once entered into lungs it starts irritating. Meconium can cause neonatal death.

Though this question has been asked long back, its not clear yet what and all this meconium can do to fetus and/or newborn.

I have no answer for the other two questions. But, lets see if any expert could answer possibly.
