How long after water breaks does your doctor induce?

Krista • Mom to Nico Orlando, Gabriella Lynn and Milana Grace. Navy wife, corporate counsel, passionate advocate for the things I believe in.
My doctor this morning said they will only wait FOUR hours after water breaking to start pitocin. That seems like s ridiculously short amount of time to let our bodies do what they were made to do. I was so shocked it makes me want to wait as long as possible before even calling my OB in the first place. Can anyone provide insight or share their thoughts? Would be much appreciated!
