I'm late to the conversation, but I'm glad you are leaving the room the colors it is. I went through this with my dd two years ago. She was almost six and had picked out the bedding, curtains, and pink wall color herself. She was really upset that her room was to be changed. It wasn't worth stressing her out any more than a move already does. At the stager's suggestion, I took down the pink curtains and replaced them with white. I switched out the bedding for a more nuetral color that went with the garden theme of the room. Dd's stuff (with her permission) that wasn't used for staging went into a box for the new house. When we walked through the house with the new owner, she complimented the room. It was the only room in the house that she complimented. IMO, it helped sell the house. I think if your rooms look magazine worthy, then leaving them as is, is fine. If they are just a hodge podge and a mix of stuff, it is better to repaint or stage so that it looks more appealing. I have seen some kid's rooms that made me cringe because everything clashed or looked like it had been thrown together with no thought of what worked.

`Beautiful floors! I would use some of your furniture to block out your space vs kids space. Put the short side of the desk on the wall where the antique radio is (line up the edge of the desk with the edge of the wall opposite). Can you get a matching black cabinet with baskets? If they are tall enough, back them up to the desk with the baskets facing towards the window. Then all the space in front of the window is for the kids and kids stuff. Put the armoire under the 1/4 round window. It will encroach a little into the desk space but it's a huge desk... Will the rug fit across-wise? Put the rocker where the armoire is for a cozy read.

All too soon your little guy will be grown out of these toys and life will change. Maybe the bulk of the toys needs to be stored in his room, if it bothers you that they occupy so much space in this room. Kids things need to be constantly edited to get rid of the junk and the stuff that is outgrown. Maybe he has too much stuff. It starts early in life. Too much stuff is not always a good thing. Sometime there is more quality play when there is not so much quantity. And, sometimes, with kids toys, opening the box that it came in is really the best part. After the parts and pieces get scattered and scribbled on, and you can no longer find that Mickey Mouse head that goes on there and the play dough has dried up inside of that tube and the Paw Patrol guys have been thrown into that basket while their respective vehicles are on the back seat of the car, the toy is not that interesting. Other than that, it looks like a room where a family spends time. It will change. You will change. He will grow up. You will grow old. Relax and let it be. Maybe put some of those things in his room and put away the art supplies somewhere else. Otherwise, consider it kid/family decor. I do quite like the dinosaur on the window sill! Someday, both the dinosaur and the little boy who put him there will have moved on. My grandson is seven years old now and the living room was a big toy box for him until I one day cleaned up and moved it all to his room. His parents did not realize that it was that time until I took the initiative and did it. That was some time ago and the mess of stuff has stayed in his room The reason is that he has grown out of most of those things and does not drag them out. Now, if I could just convince them that it is time to make his room a big boy room and get the excess junk out of there, too!

I think leave the larger toys as you are doing - by keeping them at the sides of the walls- for easy access, no point in putting heavy or larger toys on shelves as they will only keep taking them down and it doesn’t make sense for them to reach high to get them down so safer for those larger toys to be on the floor. Perhaps add a few toddler chairs around the table. You buy a book case for all the books and just use the cubby holes for other toys,
