My 2 yr 8 mth old son has an extremely active imagination. He spends most of his time pretending something or other. Unfortunately, he has now decided that there are crocodiles in the bath and is terrified of going in there! Once he is in there, he screams and wants to get out. I've tried telling him that there are no reptiles of any description in the bath, I've tried "shooing" them away, I've tried letting him bath with me but nothing seems to persuade him. He is convinced. Does anyone have any suggestions for dealing with this because I think it is going to be a real problem soon?
