Hi, I have a six month old baby boy and every night for the past 6/7 weeks, after 2 hours of being asleep in the evening he will start screaming - blood curdling screaming and there is absolutely nothing I can do to settle him. Shushing, stroking, cuddling, rocking, jiggling, nappy change, calpol. Nothing settles him. But he is also not really awake. I have no idea what to do but it's starting to become quite difficult to deal with. It doesn't matter if has napped well or badly during the day. He can have had a busy day or a quiet day, it's always like this at night. Does anyone have any advice? Thank you.
