Night owls here too, esp DH. He easily will come to bed between 4 and 7 am, sleep all day (on the weekends) or get up for work at 10 am. Me, I naturally go to bed between 11pm and 1 am, so not *quite* as night owlish, and get up between 830 and 10 am. The babies tend to stay up late and rise late-ish too. They'll usually be done for the night sometime between 10 and 12, then they'll sleep till 9am ish (nursing several times each thru the night of course), be awake for an hour or so, then take an hour- or two-long nap. It works for us, and that's the most important part. Just like BFing advice: watch your baby, not the clock. So what if a book tells you to put the baby to bed at 7pm. If she's just gonna wake up for the day at 5am, when you're nowhere near ready to have your eyes open, it's not worth it. You can always do the same routine (or whatever routine works for you), just do it at a time that is amenable to your lifestyle.
