There is no overnight miracle with bonsai care. Explain to your daughter that you are learning and it takes time. A common theme with bonsai is that the toughest thing to learn, and appreciate, is patience.
Your little tree (Chinese elm) needs to adjust to its new home environment. Learn about watering. Search this forum for the chopstick method for determining how and when to water. But basically - don't keep it constantly wet, don't let it over dry either.
Also learn about proper lighting conditions, temp and humidity.
Always remember - this is a tree, not a houseplant - a tree. You're simply its caretaker, borrowing it from nature. Nature is a wondrous and beautiful thing.
You might even want to show your daughter this forum and how you came here for help. Share all this with her and let her know how much you are trying, and how you value your gift of bonsai.
