The biggest challenge in life is to develop your offspring.We,ourselves are the image of our childhod and see the same reflection in our offspring.Though we know as a generation gap,a difference would always crop up but the animal in oneself and the haunting image of the past would always prompt one to behave the original past and would deteriorate the actual development which could have taken place.I believe it is the environmental forces and the subconscious mind which would not allow your offspring to grow the way it wants to and nurturing would never be appropriate.
