To Border or Not to Border

...That is the question. Here is my latest scrappy quilt. I made this quilt for my business partner's daughter who is 7. She is a very ill little angel and I think she needs a quilt as soon as possible. She has just started her first round of chemo to treat leukemia and I wanted to make something very happy and bright for her. Well, this sure fits the bill, doesn't it? At any rate, what I was hoping for is some input from all you quiters out there - does this need a "calming" border, possibly a great psychedelic border, or no border at all? Why can't I decide on this one? I keep staring at it and just can't seem to come to a decision. The quilt is so far outside of my comfort zone, I think it froze me up! I am stuck, for sure. Help me out on this one. I need to get it done!
