One idea could be getting her a vinyl record of her favorite indie band. You could also create a custom playlist of indie songs that you both enjoy, and then burn it onto a CD or create a Spotify playlist that she can listen to any time. Another idea could be tickets to a concert of an indie band she loves or a music festival featuring indie artists. Lastly, you could consider buying her some merch from an indie band she likes, such as a t-shirt, hoodie or poster.
Or you can get her a star map with the date when she gave birth to you.
