Remember SOS:
S = Self-awareness. You need a sense of your own insecurities, biases and an awareness of your feelings.
O = Objectivity. With that self-awareness hopefully comes objectivity. The ability to look at the world from your child's perspective and not in a manner governed by your own ambitions, dreams, fears and hopes.
S = Selflessness. This can be the grueling part. Sacrificing other priorities (sleep, work, wind down time, personal interests) to support your child in their interests, with their difficulties, and often to expose them to different activities and ideas so they can identify what is right for them.
My kids are older now, but I still run down this list frequently in my mind as a way of ensuring I am preparing the kids for life in age appropriate and healthy ways.
