Ava is the youngest of four children. She is still young enough to develop and remember core memories. A photo album would help Ava and her family document all of her milestones. A picture could be taken of her first time at the beach or her third birthday party. At some point, Ava could put her school report cards in the photo album when she goes to kindergarten. This could be something Ava can develop throughout her lifetime to help her maintain core memories.
