Compassion and empathy. Practice daily.
Also probably cease thinking like this "I've been thinking about the best ways to developer my new-born(5m+)". Your kids not a project...its another person. Love it and nourish like one, not like a project your developing.
Remember to explicitly teach all the skills that you implicitly learned, such as how to start and carry on a conversation, or how to forgive someone, or how to celebrate failure.
Set the example. Do the things that make a person a good person. The best thing you can do for children is to set the example.
