A schedule always seems like the easier option. I mean, we adults run our lives based on schedules, right? But babies thrive on responsive care. Babies grow so fast, and their needs grow and change right along with them. A rigid schedule can't accommodate that rapid pace of mental, physical, and emotional development.
No schedule doesn't mean no routine. You and your DCP will probably very naturally fall into a rhthym of feeding the baby and getting the baby to nap just by observing him and his needs. And there are things you can do to encourage a routine, mostly things that have to do with the baby's environment. A daily bath. Dim the lights and turn off the tv and stereo when you want to encourage bedtime. Stuff like that.

Coolest thing my little girl sang recently: "I love dat one-two pupples!"
