My 11 month old ds has really bad seperation anxiety and its at its worst from about 4.30am every day. He screams the house down. Currently been crying for about an hour. We've tried sitting in with him, cuddling him, giving him water. Nothing seems to get him to calm down and go back to sleep. He's got a good bedtime routine and goes down at 7pm every night. We were trying the gradual retreat sleep training to help him but so far it's made no difference. Any advice on how to help him, it's horrible listening to him scream for soloing and not being able to help.
