It is not OK to raise a baby night owl. When my son was born my husband worked nights and did not have a drivers license. I would drop him off and pick him up, and baby had to come with me. I would get the baby down to sleep only to put him into a car seat and drive my husband to work. Then I would try to get him to go back to sleep when we got home. No luck, we would be up all hours of the night. Then finally sleep, and the alarm would go off so I had to get up and put the baby in the car again to go pick up Daddy.
