second daughter, now 20 months has always been a very self-contained little girl both awake and asleep, but in the last few weeks started waking every night, 3 or 4 times, screaming. I think it's from terror, there doesn't seem to be anything physically wrong. She shares a room with her sister (nearly 5) and so I've taken to bringing her in to sleep with me so not to wake the other but it's killing me - she's awake distressed off and on thru the night and then up permanently from around 5. I'm working full time at the moment too and temporarily a single parent (husband working away). How can I work out what's frightening her and get her back to sleep? Sanity is hanging by a thread! Has anyone any advice?
