I don’t disagree with the points you’re making, but I do not think your solutions are productive ideas. You seem to be encouraging aggressive confrontation and/or manipulation, which are not only ineffective but can cause undue psychological stress for the child. Remember that between these two adults is that child who loves and looks up to both. How they manage to resolve their differences will not only have a positive or negative effect on him, it’ll also be how he learns to settle differences himself in life. Divorced parents at war with each other can be worse in the long run than the effects of interrupted medication.
