We rearranged his room last month. He chose a green paint color and we finally bought the paint this week. His Opa is an excellent painter. They made a painting date. Yesterday, they did it! His room is now green, not a green I would choose but a green that he chose because it is his room. I was happy to let him make the changes he did. As a child there are few things you really control in life. Everything is decided by your parents, teachers, or caregivers. I was just fine with him making this change.
As a child I never wanted to change my room. I kept the same blue color and curtains until I moved out on my wedding day. When I made a change it was a lifetime change. It is probably better to make small changes a little at a time!
