So many thoughts - first, it is a beautiful quilt and it is obvious that you put a lot of time and effort into it. We have talked on this board about quilts meant to be someplace. Maybe your quilt was meant to be with the 4 year old - maybe the 4 year old fell in love with it. As far as what to do, maybe you could ask your stepdaughter if she is enjoying the quilt. If she says it is with the 4 year old you could ask if the 4 year old is enjoying it. Depending on the answer you get you could say if she doesn't have room to store it, you would be happy to keep it for her til she is ready for it. I know our other wonderful board members will have more suggestions.
