We have a beautiful, happy adopted 4 yr old girl. We fostered her when she was a few months old and then adopted her when she was 1. She loves to chat and tell stories. For a long time these focused on her 'tummy mummy' - she told elaborate tales about where her tummy mummy lives (in a castle!) and all the wonderful things in her house (a swimming pool, a bunk bed, lots of unicorns, many sisters etc). She has recently moved on to talking incessantly about her 'foster sister' (she was with a different foster mum for the first few months of her life and the family was also looking after another little girl). These stories are constant - many, many times a day in response to any new information. So, for example, if we say 'some children like playing football' she will respond 'my foster sister likes football and she wears pink trainers and... etc etc.' I am not too worried about this - I think it is just her way to process and integrate new information. But my question is, how should we respond to her stories? Generally we just nod and say ok, that is nice. But a couple of times, when she has talked about 'her room' at her foster sister's (or tummy mummy's) house, I have gently reminded her that there is not a room somewhere else for her because this is her home and we are her family. When I have said that, she gets really upset. So my question is, has anyone else experienced this and does anyone have any advice on how to respond? I tend to think that just going along with it might be fine..? She doesn't ever say she wants to go live - or even visit - these fantasy homes. I don't think it is a sign of any emotional issues - she is a really happy kid. I think/hope they are just her equivalent of imaginary friend stories. Thoughts?
