I need some cute and cheap bedroom ideas

I’m moving and my bedroom need a whole makeover, like painted, the whole nine.

My problem is I’m not sure what color scheme I should go with.👀

I’m big into neutrals right now (but my mind is constantly changing) and I’ve also always wanted an all white bedroom (minus the walls, I was thinking doing gray for the walls maybe?) Now would be the perfect time to do the white buuut I have a four year old, he’ll have his own room but I’m sure he’ll be spending a lot of time in my room and the last thing I want is him staining something.🥴😂 (or maybe a black and white bedroom??)

Also I need room ideas for him as well, I don’t like doing character themes because like I said I’m constantly changing my mind and eventually I’ll get tired of it being a certain character and will want to change it.😂

But he turns 5 in August and this will be his first time having his very own room for himself. So I want to make it GREAT.❤️

Also bathroom ideas/colors, decorations, etc.

Oh and I need decoration ideas for my room or just any ideas at all. I’m not good at this.😂
