Get her a polaroid snap touch, or it’s recent reskin, the Kodak step touch. It is a printable camera that can print sticker photos of 2x3, but you can choose which photos to print instead of wasting photo paper. Seeing her photos on a physical medium would help her feel like she’s creating something tangible, and you can buy her an Instax photo album to hold her best 2x3 photos. Additionally, she can take photos of her friends and give them copies, so it could make her cool among her friends and give her more reason to take photos. It’s what I’m doing with my 9yo, and it seems to be starting to go well.
