I'm still in the first trimester, but this is a question that occurs to me often when I read about babies and sleep. How do mom's who work out of the home set up a specific bedtime and a bedtime routine?

I see posts where babies go to sleep at 6 or 6:30pm and I can't see myself leaving work before 5, even after adjusting my schedule for having a family ( right now I work until 6 or 6:30 most days). Anyone have any thoughts or experience with this? Will I be able to set a later bedtime (like 7:30 or 8pm) so I can see LO at night?
