DD is 17 months old and goes to bed without any problems. But whenever we go up and downstairs after she has gone to bed, she cries and quite loudly. She settles again after five mins max, once the 'noise' has stopped, ie after I've finished brushing my teeth. DH is on nights and she even does it at 2am when he goes upstairs when he gets in from work. We don't go into her and she goes back to sleep quickly, just seems strange.
The only difference is she hasn't got the fan on in her bedroom now as doesn't need it, so I was wondering if she is hearing noises more?
Anyone any ideas.
