Janie, I'm sooooo feeling your pain right now. We're up to night 4 now of insanity - DS is waking constantly, and I mean CONSTANTLY. I was just in with him, waited till he was sound asleep and then stayed to see what happened. He is sound asleep, starts crying in his sleep and then wakes up.
Give me strength, there he goes again...I seriously can't do this for much longer...Dh is out too so I'm on my own (not that he is able to settle him anyway

), thankfully DD went to sleep without much fuss.
