My ds (3.5) talks a lot about his imaginary friend, down to such details as where he lives and how old he is. It comes up more and more now. Now I know I shouldn't be basing my parenting on what I see in US comedy shows but last night on Desparate Housewives, Lynette was told that her son's imaginary friend might have appeared as a coping mechanism or reaction to some upsetting event. Help! Is my poor son reacting to his dad being away for 6 months (although he's been back for 2 months now) or the fact that I shout too much?
