A 5-Hour Baby Sweater set? Those are easy and (obviously) quick. Let me see if I can find the version with the hat and booties really quickly...http://www.bevscountrycottage.com/kp3.html
Oh, goodness, there are SO many beautiful baby patterns out there that aren't hard or time-consuming. Make some gender-neutral color, or a favorite sports team's or the like. I'm jealous...you get to knit for a baby!
