I shared a room with 2 sisters... we had bunk beds where my step-sis was on top, and my little sister and I shared the bottom. I HATED sharing the bed!!! Especially when she was potty-training and I would wake up in her puddle...eew. lol. Also, if she had a restless night or a bad dream, or even just wanted to roll over it would wake me up, and vice-versa... so we spent half the night waking each other up! Also, when one of us would be in a bad mood, we would pick on the other (you know how kids are)... I think it would be a lot easier to put them in separate beds... especially since they have different bedtimes.
