Again, I suppose only a professional could explain why she would be more friendly toward you than her children, expecially the youngest. I'm glad you spoke to the school counselor and I hope your son will open up. He probably will be the one to be the most resentful toward her. The five year old is more easily to adjust and to forgive.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
