My ds is still in his crib and we plan to keep him there until he starts climbing out. He is two. He doesn't seem ready for a twin bed quite yet, I'm guessing we might wait until he is 3 years old. But I found this absolutely adorable kids twin bedding w/matching valance set at a local TJ Maxx and there were only a couple of them left. Would you buy the bedding in advance (knowing that he will be in a TWIN sized bed when he stops using the crib)? It matches his room decor and is fairly reasonably priced...WWYD?
