My job position. I volunteered at Labor and Delivery Kaiser, and Birthing Center Sutter Hospital.?

I volunteered at Labor and Delivery Kaiser, and Birthing Center Sutter Hospital. What would be my job title for each? At Kaiser I got to hold the newborns and take care of them, so I was thinking something about "Newborn Care". And At Sutter i was dealing with pregnant women, so I was thinking about putting down "Delivery Aid"? but I want to put down something better. Help plz =P
