Ok. History: dd always slept well, so well I used to wonder if everything was normal. Then at Christmas went to stay with relatives. Couldn't fit cot bed in car so decided she could share our bed. Then till Monday she has spent every night in our bed. Monday we decided that she was staying her in cot. All going well till last night, all we've actually achieved is us staying in her room with her all night.
Any advice welcomed. Although we already tried and are using the following, a pillow, a beddy bear, clipping her dummy to her, turning her cot so that she sleeps the same way as she would in our bed.
