Personally thinking of my relationship with my future children can be daunting. However I know this is a simple fear response that has little bearing on reality. Understanding this is important, things are easier and simpler than they seem. The first step would be understanding them and yourself, before that you will be acting blind and at best puppeting yourself to act as you "think you should". I apologize if this is too vague, starting from a general view is how I have found is best.
