Last night DS13 was in tears. He tried to hide it but eventually admitted he was upset Christmas is over but also that he felt it hadn't been as exciting as in the past and that the magic has gone. Is this just part of growing up? He was worried this means a broader problem and that he might have depression. I tried to reassure him that feeling sad is normal at times and that Christmas inevitably changes as you grow up, but secretly I am concerned that he is so sad and worried.
