Daughter seeing things?

Hi all, I just need to write this down cos I am a bit concerned/worried/scared I dunno! Anyway any comments appreciated :) my second dd was stillborn about 7 weeks ago at 39 weeks. My first dd has taken this fairly well especially since things have calmed down in the last few weeks. Anyway on three occasions in the last few days she has bought up that she is talking to this little girl. Only just now I was in the other room and heard her talking and asked her what was going on. Her response was I am just talking to the little girl walking over there. I asked her what she looked like and she said that she looked like a fairy. Yesterday she told me that she was talking to the girl from heaven??? Now I don't really know what I believe in all this and I am thinking this is her way of coping maybe given that she was supposed to have a brother/sister at the moment and obviously doesn't have a baby at home. I am just not sure what to do/say to her...do I nurture this? I don't want her to feel like she can't talk to me about anything or think she is different in anyway. I am just confused! She is 2.5.

I would nurture it as much as you feel comfortable. They say children are so much more open to everything then adults. As long as she is happy then I see no harm in it.
Big hugs for you all though, I can't imagine how hard and strange this might be.

I would talk to her about the little girl she sees- what shes llike etc. sounds toe like She's got a guardian angel looking over her and the little girls jut wants her to not be scared. Xx

Thank kazoo and bright sparkles for your responses. I thought the same to that I should just nurture it and let it be what it is. I have to put my own fears aside I think! There have been three times she has bought this little girl up now and each time I try and get a bit more info from her about it - like her name/hair colour anything that she really wants to tell me. She has really good speech for her age so can tell me a lot but I think she intuitively picks up that I am a bit freaked by it so will change the subject after a couple of comments...:)

I think its a lovely thing your daughter is experiencing. And its really great that she has talked to you about it. I know it can be scary but try not to freak out. I hope instead you can take some comfort from it.
Hugs.
You have been through so much. I'm sorry your baby couldn't stay longer.
