I agree - it's such a beautiful thing to witness, especially because they're so unabashedly proud of their creations. The confidence and fearlessness is so sweet. They have no idea what self-doubt is at that age, it's so pure and precious. My cousin once created a "bug hotel" complete with intricately crafted rooms and an outdoor garden area with a tiny pool for the bugs to relax in - it was so cute and imaginative! And she explained her vision to us with such enthusiasm and certainty, like it was the most obvious and brilliant idea ever lol. Kids are the best.
