Well babies themselves are drawn to look at primary colors and areas of sharp contrast. They are particularly drawn to the human face. (Two eyes, nose and mouth) That's what they taught us in Childhood & Developement, so I'd go with that. One of the ladies here on the QB also was raving about how much her grands loved their quilts with minky backing and how they call them their "get nekked blankies" to cuddle up in after bath time. I thought that was so precious!
