You mentioned that you are not an early person and get up at 10AM and go to sleep around 3AM. Do you and your wife have the same chronotype? And if not, does it cause any tension?
We are the same type under ideal circumstances, yes, but these days we’re not synced up much because of Oliver. Stacey wakes up early with the baby (usually around 6/7AM) and goes to be earlier at night (around 11PM). I tend to feed Oliver before I go to bed at 3AM and a few hours later he’s up with Stacey.
We’ve never been the type who worry too much about going to bed at the same time or waking up and the same time. On weekends we tend to both be up later and sleep later where possible. Since we don’t tend to do things early in the morning, sleeping later than her means I don’t miss much (other than precious baby play time, which is a shame), and staying up later means I can watch terrible TV without worrying about being judged (or spend extra time with the Xbox 360).
