Oh Sacha - Oliver did this exact thing last night!! It was awful. About half an hour after he fell asleep he woke with this horrible scream and I couldn't settle him. He wouldn't take the breast at all (which always settles him) and he just screamed and screamed. I thought he might have been bitten by something cause I couldn't work out what it would be. He's never done anything like this before, and when he finally did go back to sleep in my arms everytime I put him back in his cot he would scream again. It was nearly two hours later when he was finally back in bed. Poor thing. To make matters worse DF was away for the night!
