My little girl is 8 months old and has suddenly started waking at night, always around the same time. She's always been a great sleeper and has slept through the night since she was 2 and a half months old. For the last week she has woke screaming and will not settle and go to sleep until I lift her. I've tried settling her in the cot, tried soothing her back to sleep but she just wont have it. As soon as I lift her she stops crying and is asleep in seconds, but will wake after 5 mins of being back in the cot. Any tips? I do not want her getting used to sleeping on me at night!
