Have you been in the birthing suite? What was your first impression? In my experience the feeling you get as you enter a haunted room tells you the intention of the spirit.

If it were me (being a Christian) I would take in a rosary or a bible, or even a prayer card with me. If that's not your bag then a piece of black tourmaline will do the job (available online, just google) which will basically tell the spirit that you are not interested.
