I assumed my dd was talking to me this morning when she said 'mummy can I X' but it turned out to be directed at our childminder. I questioned this and she said 'oh she's always called me that when you aren't here - usually she stops when you get here instantly and starts calling me X - she definately knows you are her mummy' She's 2 been there since she was 6 months. I didn't really say anything, but I'm sitting here fuming - does this matter?
