My daughter aged 4, has had an imaginery 'grandpather', 'cousin' and 'big sister' whom she says lives round the corner with a big garden and she also has a rabbit! I am beginning to wonder how to deal with it, do I agree with her & amuse her, which I have been doing, but she wanted to go round to her 'grandpathers' last week to the point she had a paddy on the floor because we had said OK earlier in the day just to get her out the door, so when it didn't come about she went off.....crying etc. so this did worry me about the way we're handling it, any advise....??
