It's actually fairly common. I went through it was well. Like previous poster stated they had specialists from the nicu there just in case there is a respiratory issue. Other then that, when your water breaks it will have a greenish tint to it. The tar diapers were normal in my case.
It depends but if they notice before gou deliver.they will have nicu staff at thw birth and they try to make sure the baby doesnt breathe before they're able to suction its mouth out then theyll put the baby on an antibiotic to make sure.they dont get an infection.in their longs. My son was born in very thick meconium. He had all his tar like poops come out during labor. He didnt breath for 7 mins
