Do doctors have a life outside of work?

I'm considering becoming a doctor but I really would love to have a family and I want to spend time with my kids and be able to take them to their baseball game or ballet recital and be there for them but I also want to have a job that pays well and I can enjoy. I was thinking about becoming a radiologist, radiation oncologist , hematologist, OB/GYN, Pediatrician, which one gives me a flexible schedule (or atleast normal, no irregular hours or random call ins at 2 am, or atleast not too many) and pays well too?
