I wish I could be helpful but I don't get girly. LOL
How about her own ipod (or MP3)? OR maybe giftcards to like the movie theater and her favorite place to eat to have a "big girl" day with momma? (I am actually considering doing this with Landon because he always wants to "pay" when we do something)
That is all I can think of. If I think of anything else, I will let you know.
