Last night, after a long 7 hour train journey back from my in-laws, my 5 year old daughter unlocked the door and walked out into the night. It was 8pm and she had gone to bed at around 7pm. She wasn't sleep walking, neither was she distressed in any way. We had had a good 5 days away which she enjoyed. She was also happy to be back at my parents for the night before we went back to our house today.
I am struggling to understand why she decided to unlock the door and walk outside on her own. She had got out of bed, dressed herself in her school uniform (she does not go back to school until Weds - she attends school in my parents' village) and walked for about 3 mins up the road. We only realised when I got up out of the lounge and saw the door wide open. I shouted for her and she came running back. When we questioned her she said she didn't know why she did it, giving excuses about seeing her friend and going to school which is about a 5 min walk away. Obviously we are all concerned and will no longer keep the keys in the lock. However I want to understand why she decided to do this. She is a string-willed, very imaginative child who is very into stories about children having adventures. I am just wondering if this is the reason for it. Does anybody else have experiences of their children 'escaping' in the night? I must add that we all get on well and there have been no fights or issues which may have led to this. I have not disciplined her for it, just spoken to her rationally about what could have happened - cars, getting lost etc.
