Schedules for Babies

Now that I'm back to work I really want to get Owen into a routine/schedule.  We've always kind of had one, but I'm thinking it should be a little more set in stone now.  I know some people are totally against any type of schedule for a baby, but I figure it can't hurt to try.  Especially since it seems that when Owen is up too long, or asleep too long, he turns into a total crabby face at about 5:30.  That's usually the time I get home from work, so I'd like to be able to spend time with a happy baby, not one who just wants to scream at me all night.  Today marks day one of our much more structured eat play sleep schedule...here's to hoping for a good day and a less crabby evening.
