Weāve kept it very simple, walls are white and we got decals from Etay and brightened up with a few accessories, mainly animal/jungle themed
Weāve also got a random tent in there which I got for free, so thereās no colour scheme or anything š¤£
My lgs room is a very light sage green with sage green wallpaper with rabbits, hedgehogs and foliage in white. Then she has framed Winnie the Pooh pictures. The thought process of changing up the pictures as she grows with room not feeling to babyish but you could choose a paint colour and then do something similar and change up with pictures to whatever he likes as he grows A lots of people I know have white walls and then some artwork that reflects itās a childās room (as well as their toys)
