You might've noticed by now that your baby is developing activity patterns, and if you've been kept awake at night by a kicking, punching, disco-dancing baby, you might've also noticed that your schedules aren't matching up. But don't be concerned about that: It's totally normal, and it could be that you're noticing nighttime activity more because you're quiet and resting. Consider it practice for those early days of parenthood, when the little guy will want to sleep peacefully all day and party all night.
And don't worry if you haven't detected any baby sleep-wake patterns; it's early yet, and you might never get a handle on it anyway. There's no clock in there, after all, so the baby's habits are likely going to change frequently. It's nothing to lose sleep over, so enjoy your rest now while you can.
