My DD who's 1 (19 months) currently has her own room, she's afraid of the dark and won't sleep unless her door is open and the hallway light is on all night long. My DS is currently 5 months and when his 6 months will move into either his own room we currently have a spare room empty which is a small room or in with his sister, obviously once they are both older they'd have their own rooms if they did share to begin with. I wasn't sure if having them sharing would help my DD sleep better and my DS wouldn't know any different, his a good sleeper atm! What's everyones sleeping arrangements when it comes to siblings?
