... on their own. I have been leaving mine to play on her own, with the free roam of the upstairs of the house, gate on the stairs, since she was one. Some have suggested that this is not the responsible thing to do, but I strongly disagree. She clearly loves her own company, she is up there now having a great time, no idea what she's doing but I am sure that it will take me half an hour to clear it all back up!! I think that it encourages her to enjoy being on her own for varying periods of time, at the moment I don't leave her for longer than half an hour. Teaches her to be more inventive as she has to learn to entertain herself. And most importantly, it just gives her the chance to be on her own, which she doesn't get very often. I know that there is a small risk of her hurting herself, I really have not got a clue what she's doing up there and it's just gone silent which is a very bad sign!! But I can be there is a second or two anyway. And it is a bit of a rest for me after having to look after her since six this morning. So I doubt if I will stop doing it but would love to know what other people do or have done or would/will do.
