This was such a heartwarming read. All this small step creativity is impressive, especially the lore she's building. I must say, not every child can express their talent through drawing, and that is fine.
Storytelling and music are other forms of art, too, that children can express themselves. But I also agree that mistakes are very important. When we do things physically, without an "undo" button, it teaches us patience and also resilience.
We have to fail more as kids, so we can have much higher-level failures as adults. I think a lot of young adults today are failing at things they should have learned as kids.
