Just go to the hospital and explain and ask if you can have a minute to check the light in the room, meter around all the shadowy things you may encounter and you'll have a good sense of what your aperture/shutter speeds should range from.
Are you shooting the actual birth? Head coming out and all? Or just the baby once he/she is already born? Congrats!
