My Mom didn't sew (only fixed things) Both grandmothers did. I learned at a 12 (making clothes) Neither of my daughters are interested. It is too easy to have MOM do it.
I didn't take up quilting until I was about 40. As to your DIL, leave her be. She will ask for your help when she is ready. Meanwhile, show her all the great stuff you make and gift her with something once in a while.
