My lovely beyond lovely little boy who will be 8 in December will spend every waking hour playing THE SAME game, at present and for the past few days it has been re-enacting Thomas the Tank Engine. He will watch it on TV and then spend every moment we are at home pretending to be a train, running up and down the length of the front room/dining room. Other days it's Peter Rabbit or whatever movie he's just watched. He has no interest in toys whatsoever - none, not even toy trains when he's being Thomas. His toys are never touched. All he loves to do is re-enact his latest favourite TV show etc. He is such a happy contented boy but I do sometimes wonder whether this is normal behaviour? What do you think?
