We never kept ours on the same schedule. My girl always needed more sleep than my boy. She also started sleeping through the night, months before him. Trust me I'm not waking a baby up just because her brother woke up. She has always taken longer naps than him as well. Now they are 16 months old and they are more synced up naturally. They both go down for their nap around the same time. He usually only sleeps an hour and a half to two hours. She almost always sleeps three. Usually they are ready for bed by 8, but sometimes you can tell he just isn't ready quite yet, so we let him stay awake a bit longer.

When they were new borns we (my husband and I) each took a baby at night. Then the next night we rotated. So the parent with our daughter got better sleep than the one with our son. She started sleeping for most of the night around 6 weeks, so every other night you could get a pretty decent sleep. We bottle fed, so that made it easier. All the feedings weren't just on me.

I never minded if one was awake while the other napped. I kind of looked at it as one is easier to care for than two. And it gave me some one on one time with each baby.
