DS is now 18months, up until 3 months ago he had been happily going to sleep by himself for naps and bedtime. Then he suddenly started screaming when I left him and since then I have had to be in the room while he goes to sleep. This is not a problem wtih naptime as he goes to sleep really quickly. However bedtime is a different issue, he used to take 10-20mins and I thought we had finally reached that point again with me just sitting in the room - I had been gradually moving towards the door and reached the point where I was right at the door and he was totally happy. But the past few nights we've gone back to it taking around an hour on average and DH has generally had to step in and stroke his back (I'm 37weeks pregnant and can't physically manage this anymore!) This is a recurring pattern and every time we make progress it gets bad again for no reason that I can see. As he sleeps through I would normally grin and bear it but I'm just starting to freak out a bit because of the impending arrival of baby number 2 - I have no idea how bedtime is going to work if I have a screaming newborn in the room with us! DH will not be able to be here all the time due to work. I'm as sure as I can be that he is ready for bed at that time, he has a peaceful bedtime routine...is there anything we can do?
