Individuals can take care of the "baggage" of life and give to children what our childhood may had so tragically lacked, needed and wanted. This can serve two purposes: 1. To give a child what he/she needs to grow into happy, mature adult and 2. Help us to heal by experiencing what should have been. I didn't have Little House on the Prairie growing up but I'm trying to give it to my children (if you mean a wholesome life).
Technically no childhood trauma - either sexual, violent, or both can cause actual reduced structural development in the brain. Do a search on "brain structure" and "trauma". Or get a recent book on post traumatic stress counseling. The brain can develop work arounds, but it isn't quick or easy.
