I can't quite believe that anyone would get rid of something so special. I would definitely hang on to it. She may appreciate that you did someday. Right now maybe she's just too busy or whatever to realize. Then again, some people just aren't sentimental.
I have all my kids special hand-knit clothing, blankies, etc and even though all my kids are boys they really want me to keep them for "someday". I guess the nut doesn't fall far from the tree or whatever that expression is :D
