  • That's how high the baby is. 0 is when the head is right at your pelvis and anything "plus" 1, 2, 3 is the baby moving down and crowning past the pelvis.

  • There are little bony prominences in your pelvis called the ischial spines. These can be felt in a vaginal exam. When the baby's head is right at this landmark that is "Zero station". When they say you are "minus three" it means your baby's head is three centimeters ABOVE the ischial spines. When they tell you while you're in labor that your baby is "plus 2" it means the baby's head is 2 centimeters BELOW the spines. Does that make sense?

  • That is a chart to show you what the stations look like on the pelvis.

  • In more general terms, it means your baby hasn't dropped yet. :)

  • It means the baby is coming down but is not fully engaged in the birth canal yet. You'll probably be having a baby soon though.
