What is the purpose of baby oil?

Silly question, but what is the purpose of baby oil? I've often thought of this and have never asked this question. My bottle of baby oil seemed to last me through all of my children and then we threw it out because we really didn't use it.

    I used it for my babies when they were young and used it sometimes myself. I loved the scent and how it left the skin soft.
    Same here.
      I've used it to shave and my skin gets very dry. So, I use it on my skin. I love the smell.
