I was saddened to read that Dr Wendy Greengross died. She literally saved my sanity with her down to earth common sense on her radio programme in the 70s. I had just had my second child and the older one was exhibiting jealousy and the situation was very difficult. Then I heard Dr Wendy on the radio saying that jealousy was natural in this situation and if it was suppressed it would warp the child's personality as they grew older. Her analogy was 'how would you feel if your husband came home with another woman and said this is my new wife and we are all going to live together'? I have passed this advice on many times and never forgotten it.
