For a child, a bedroom is more than just a place to sleep. It is a place to do schoolwork, listen to music, play games, sprawl on the floor, rough-house, read, build models, daydream, visit with friends and keep innumerable possessions. You’ll need to plan carefully to create a room that serves all those functions, is comfortable and inviting — and has enough staying power to require only minimal redecorating every few years. The ultimate experts on what kids like best are kids themselves. Make kids feel involved in the design process by letting them help with selections for the room. Include the children’s interests and ask for their opinions as you create a decorating scheme. But don’t go overboard: Children’s interests change often, so use accessories that can be easily replaced when interest wanes. What you want is a room that both meets your needs and pleases your child. The furniture and accessories should be appropriate for your child’s age, but they should also be adaptable, not trendy. Pick baby and children’s furniture that can grow with your child — and any siblings who might be sharing a bunk bed. Also, plan to provide space for the many activities that may take place in a child’s room. This includes space for visiting friends and sleep-overs, a place for play (remember to have room for a train set or dollhouse), and a spot with a desk and good light for doing homework. Children should have a sense of control over their environment. They should be able to hang up clothes, reach toys and books, and sit in chairs that suit their size. An added benefit: They’ll learn early that they can do things for themselves
