Add a lot of details. For example, if you're talking about a day at the park, don't just say she played. Describe the color of the flowers she saw, the type of ice cream she had, and the new friend she made there.
Another great idea is to record voice memos. Every time there's a story, quickly record it on your phone. Then you can store all these voice memos in a dedicated folder. This way, you can always listen back to the stories in her own voice as she grows up.
One time when babysitting my little niece, we had a great time making cookies together. She was so excited to pour in the ingredients and stir the batter. We made chocolate chip cookies and she ate three right away.
Well, once my little niece saw a little puppy on the street. She was so excited and immediately asked if she could pet it. When she did, her face just lit up with pure joy.
One memorable story was when she dressed up as a princess for Halloween. She had a tiara on her head, a pink dress, and a little wand. She was twirling around the house, saying she was going to cast magic spells on everyone. It was just adorable.
You can start by setting aside a specific time each day for study sessions. For example, an hour in the evening. Sit with her, help her organize her study materials, and go through her school work together.
Once, my little niece made a handmade card for her mother on Mother's Day. It was full of cute drawings and sweet words, showing her deep love for her mom.
