Sometimes kid fabric can be worked into a regular quilt (unless it's the licensed stuff) and looks great. I'd definitely keep it. You will like it way better after awhile. I often feel that way after finishing a quilt with a very controlled color range and have to move on to something completely different.
Btw, another reason to keep it is that many fabrics are being printed on cheaper and cheaper goods, so that the value of what you have is going up. I just pulled from one of my earliest stash boxes and was stunned to find out how substantial all of it is. I am also using 2 older Shadowplay fabrics in a quilt right now, and 2 new pieces purchased recently are waaaay thinner and very silky. It totally loses the velvety look that the older ones have.

Charlotte, who is not going to be fooled by the upcoming week of sun. We've seen this movie before.
