I have this book at my home titled: Moral Theology by Rev. Heribert Jone, O.F.M. CAP., J.C.D.  
Also Rev. Urban Adelman, O.F.M. CAO., J.C.D.  1948

When I was very young I remember hearing conversation in the kitchen from my mother and a lady friend talking about a child that was baptized before it was born.  Never heard that again and never read anything about it till, yesterday, while dusting off my books I happen to open to the pages about baptism, and yes it does say there is such a thing as BOB and BOD, and also tells how to Baptize before birth.

Word from word I typed and checked for errors this is what it says:

If the head alone is delivered and there is danger of death, Baptism is administered thereon, no conditional repetition being subsequently necessary.  If death threatens after another member is put forth, Baptism is administered conditionally upon it (si capax es). Should the child survive birth, Baptism must be repeated conditionally (si non es baptizatus).  – If no part of the child is delivered it can be reached with a syringe and baptized (the child itself being reached and not merely the amniotic membrane).  Baptism is administered conditionally (si valet), since many doubt the validity of such a Baptism.  If the child is thereafter born alive, Baptism is to be repeated conditionally.

Should the mother die before the child is born there remains the grave obligation of charity to baptize if there is any home that the child is still alive.  Such a hope is generally not had if the mother dies within the first four months of gestation.  Should the pregnant woman die and the child still probably be alive, it should first be baptized conditionally in the womb as best it may and then extracted and conditionally rebaptized.   The priest should not fail to remind the deceased mother’s  relatives of this obligation.  To avoid legal implications and scandal the priest should neither order a Caesarean section, nor undertake to do it himself.

   

Yeah, that's true. I remember how my mother told us that the nurse or doctor immediately baptized her first child (and that's my eldest brother) when she had a miscarriage due to sickness.
