This type of project can be fun, done with the children, and quite affordable. You really do not have to go out and hunt for the perfect color for a kid s room, nor do you have to hire a professional to paint those walls.
Lets walk step by step on a easier way to get paint on the walls.
Then we will further dig into what else can go on the walls as well. This keeps the paint from getting on those areas. If you are mechanically inclined you can use a screw driver to remove door handles, outlet and light switch covers but if children are helping it is best to use the tape for protection. Use the drop cloth to cover the floor after you place the tape the floor molding. Well, from the answer of junior, you got tons of ideas to begin with.
