Charlene,
This is really cool!  I love your innovation of the ribbing at the back...I agree, a traditional hat wouldn't keep the baby's neck warm, and that's very important during the winter months.
It's also cool how you didn't have to do any seaming...LOL, you know how I hate seaming!  Another thing I like is that you used the Simply Soft on the inside and the Red Heart on the inside.  I like the sturdiness of the Red Heart, but hesitate about using it for anything worn by a baby.  It's not very soft!  (I also cringe, remembering years ago it used to be about the only worsted weight available in an acrylic, so I made many baby items with it.  Argh.)
