This truly was a breeze to make.  I think it took a week from start to finish.  And, it was one of those projects that I picked up and knit here and there.  We were traveling, so I didn't have that chunk of time I usually have in a day.  
I dug into my button stash and choose navy buttons to match the navy romper.   (I love all the colors it comes in!)  I think an outfit is always a nice gift for a new mama.
