"Sudden Birth" (https://archive.org/details/sudden_birth). Why you ask?
1.) It's a short educational film teaching police officers how to birth a baby. 2.) The film shows a live birth in the back seat of a car. 3.) the best advice the movie gives is to "hold on tight to the baby, they are slippery!" Thanks for considering!
ps- I was at the State theater tonight and it was fantastic! I heart you all
real hard!
