shutting daddy in the bathroom

Last night not long after Chris had gone to work, Amelie woke up and her room was freezing despite the heating being on so I brought her in beside me. I was then woken again, around about midnight, to find her not in the bed!! I found her in the en-suite a little bit confused. I think she was looking for her dummy, the little monkey. She had obviously managed to get down from the bed (its quite a low bed and Chris has taught her to go down backwards so she doesn't go head first and hurt herself). From now on - if she is in with me I'm shutting all the doors or who knows where I might find her!!
