My toddler has been a great sleeper for the past 7-8 months, wanting to go to bed in her cot and sleeping through the night. However one night last week about an hour after bedtime she woke up and started screaming and screaming and refused to go back into her cot. Since then she has refused to go anywhere near the cot, so we have to put her down to sleep on our double bed, creep out when she's asleep then one of us sleep on the bed with her. We have tried moving her to the cot when asleep, but then she will wake up in the middle of the night screaming blue murder again . It feels like we are back to the early months again, creeping around trying to put her to sleep and creeping out of the room in case she wakes up. If she knows there is nobody there she will wake up and start screaming. Any advice please?
