How about a mother's ring with all the kid's birth stone's in it. I know I would love one of those. Or now of days they make bracelets and necklaces that are the mother one's.

What is her favorite movie? Maybe you could buy her that movie with a tin of popcorn and a throw blanket. My kid's did that one year and I thought it was sweet. In their card they wrote how much they loved me and how hard I work. So this gift was for me to relax, throw on my blanket and have a snak and relax watching a movie.

Or the homemade gifts I always treasure. You could maybe take that cutie little girl of yours to a pottery place and let her make something.

Other then that what are her interests? Does she have a hobby?
