I'll go first.
When my son was about to turn 5 years old, he wished for a Rocket Room Decoration for his birthday. I searched for weeks but couldn't find anything that felt right. The night before his birthday, my husband and I were always decorating the house. Because his birthday is in December, we always wait to put up holiday decorations until after his party. The day before his birthday, our neighbor gifted us some paint bottles. So, I put my son to sleep in our bedroom instead of his room and decided to paint a rocket on his big wardrobe. I also used chalkboard paint so he could draw on it, and I glued some lights around the flames at the bottom of the rocket. I was busy with it all night, and nobody else in the house knew about it until the next morning. He was so incredibly happy; it was worth it. Today, he is 19 years old, and since then, every evening he turns on the rocket lights on his wardrobe.
