thanks so much for your support, I know to expect some regression but its been five bad nights now so I hope it doesn't last much longer! I've been really trying to stay consistent but am struggling to keep him in bed for the day sleeps as I am close to the edge and would rather get him up than get angry when he fights it for so long. Other than that, we have a good four hourly routine, no props to sleep apart from the occasional head-stroking and shushing. I am perservering!
