“Why do you like IFS but not ‘Self-led parenting’?”

Coercion, including covert coercion imposed with a soft voice and loving words, is deeply disconnecting, and it certainly does not feel compassionate to the person on the sharp end. What seems to be called ‘Self-led parenting’ is a far cry from the deeply respectful, non-coercive spirit of the Self of IFS when they are talking about adults.

“How can I become more aware of anti-rational parts in my mind?”

Drop the second guessing and scrutinising and judging. It is as toxic for us as that kind of thing is for our children. If you are not feeling free—free to think, free to be and free to act in accordance with your own ideas, your thinking flying free as a bird—it might be that you are seizing up your thinking with scrutiny and judgement, objectifying yourself as a parent.
