9. Think ahead.It's easy to put too much emphasis on the stage your child is in right now, even though we all know they grow so fast. Save yourself time and money by thinking ahead and making a few design decisions that will pay off in the long run. Choose classic and basic over cutesy and cartoony for pieces that will stay in the room for some time, like lamps, curtains and rugs. And consider versatility. I have been seeing more and more daybeds in kids' rooms lately, and I love it. You can put one in an infant's room and use it to rest on during nighttime feedings, then transition it to a toddler bed when it's time to move out of the crib. In fact, if it's a twin-size daybed, it could work for your child all the way into the teen years, and it usually comes with a trundle made for sleepovers.
