I know this sounds like something people would say "all babies do" so please don't judge. But my baby has recently started waking up really screaming. He will only do it maybe once or twice a week, and it's not like he's in pain, but he is really distressed. Almost like he's still asleep though, but really screaming. It will only last maybe a couple of minutes then all of a sudden he will calm down and settle back to sleep. I'm finding it quite stressful as I don't know what it is that's making him so upset. I thought maybe it could be as I'd recently moved him in to his own room, and maybe the new environment was causing him to be unsettled, but he will even do it if I've bought him back in with us. Generally early in to the night, when he's been asleep no more than a couple of hours. Has anyone else experienced this??
