Jdub, I hope your nights have gotten better, if not, we got the days and nights "right" by implementing a hard wake time. We feed the boys on a 3 hour schedule and will continue to do so until they're sleeping 10-12 hours at night. We do a feed, wake, sleep, feed... schedule.
Our hard wake time is 7 AM so we wake them up for the day, feed, keep them awake for a bit if we can (change clothes and diapers, etc.), then put them down until 10 - we continue this at 1, 4, 7, and just before 10 we do a bath and put them down - at night we don't allow wake time it's feeding and putting them down right after burping. At night we let them wake to feed rather than waking them up at the 3 hour mark, so no matter what time we do their last "night feed" (even if it's at 5:30) we still do a 7 AM wake time.
We were already doing 3 hour feeds during the day, but we had been letting them wake naturally to eat, but they were awake a lot at night and super fussy, something about implementing a hard wake time ironed out their days and nights after about 4 days. Now they have a bit of wake time after their daytime feeds rather than being awake after their nighttime feeds.
We try to always wake them up for the day within 20 mins or our usual 7AM wake time - sometimes we get off during the day so they get put down for the night at a different time, but we're not going to try adding a hard bed time until they're sleeping at least 8 hours on a normal night. We're doing all of this based on the Baby Wise model of parenting based on the book "On Becoming Baby Wise: Giving Your Infant The Gift Of Nighttime Sleep"
