How about tickets to a show or a gift card for a local movie theater. Books about America for the teenager would be a nice gift too!!! Or....how about books about Russia for the mother? A really nice book would be about how to raise teenagers. :)
Movies are always great. How about some classic movies for her and her new daughter to watch together? Like.......Pretty in Pink, Breakfast club, Sixteen candles, Footloose, etc. Good luck and congrats on being an aunt. :)
