I have two boys: 23m and 3.5y. My oldest has expressed interest in having his younger brother move into his room and they would share a room. I'm a little nervous about this because currently they both sleep GREAT separately and I don't want them to keep each other up (or to wake each other up early). I'm also nervous because my youngest isn't vocal enough to be able to tell me if he likes the idea of moving into his brother's room or not.
