If a person went to a Polish hospital (wartime) in the city would they likely have kept records of births?

I tried to find out from the Urzad Stanu Cywilnego in Lublin about obtaining a birth certificate and had no luck. I am not sure if my grandmother employed the services of a midwife. What I would like to know, if a person went to a hospital in the city would they likely have kept records of births?

If so, how easy would it be to obtain a copy of the record and what requirements are needed in order to make the request?

It is highly unlikely that she went into hospital to have a baby. Most hospitals were bombed during the war years. She would have had to register him and have the baby christened. This might be your best bet. Go or get in touch with the local church where the christening would have taken place. This might give you further clues.

And before the war it wasn't common to go to hospital to get a baby, people were doing it at home.

Thanks. It was worth asking since I had asked the registry office in Lublin if the birth was registered and they had said no. That is why I thought if my grandmother was living in Lublin during the war at the time she was pregnant than she might have gone to a local hospital.
