I am very sorry that you have these severe issues to cope with.
Obviously your six year old has complex issues and as a very experienced Mom, I guarantee you no Mom could handle all those
behaviors and raise a smaller child. You do have too much on your plate.
I have no knowledge of how your system works so I can't really make any suggestions for getting help. Obviously help is needed
and it is needed now. Perhaps if your social services system
and your school system are not addressing his needs, there is a
legal service available to help you? or an advocate?
As a former child advocate and guardian ad litem, I must ask you
if you have a fail safe method of protecting your little girl from her brother. She is so vulnerable at that age and his abnormal interest in sexual activity puts her at risk. Does she,
for example, share your room??? Has your son been abused in the
past?
Sorry I have no answers but want you to know that I am thinking of you and yours. DDD
