Try to choose furniture that will grow with your child and his changing tastes. Sturdy oak or cherry furniture with classic lines will blend in with almost any décor and will last for years. White furniture will provide a similar blank-slate background against which you can change your bedding, rugs, wall coverings and window treatments, and white is a favorite color for many girls' bedroom sets.
If you are planning a room for an infant or small child, you have an opportunity to consider furniture that will really be flexible, as there are now cribs that convert to toddler beds and finally to adult beds. Choosing such a convertible piece in a durable material and classic style will save you money, enabling you to possibly splurge on smaller, fun items for the many different rooms your child will want over the years.
