Start with a theme and think outside of the box. Avoid room themes that are based on your child's favorite character or television show because it will be difficult to design the room without having to purchase a lot of overpriced and unattractive room d├ęcor created to market specifically for kids. Instead, select a theme that is more general based on a broader interest of your child, such as a flower garden or the solar system.

Allow your child to become a part of the process. Talk to you child about their specific tastes in colors and other room details. Ask them about what they would like the room to look like; perhaps they will have an idea that is lots more creative than anything you might see in a magazine or catalog.

Use a great paint color but think sophisticated rather than Crayola crayon. Select a paint color that is subtle, subdued and classic. Allow the brighter colors to come from accessories and your child's toys, these items will inevitably be brightly colored.

Make it personal by incorporating your child's name somewhere in the room. Perhaps you can stencil their name on the wall above the bed. Also, rather than spending money on store bought art work, use inexpensive plastic frames to display your child's artwork and other creations.
