Once you understand that the primary purpose of your emotions is to guide your thinking, you no longer need to over-rely on cold rationality to make good parenting decisions.
Your decisions can be "emotional" without being irrational. (They may, however, transcend conventional rationality.)
The key is to be willing to wait. Take no action until your emotions give you the green light, because your culturally pre-programmed answers come up immediately, while your creative process may take more time.
Often a particular choice seems very reasonable, but you feel something isn't quite right. Connecting with the feeling and waiting for more clarity will reveal another aspect that, when considered, leads to a better course of action.
If you have a history of indecisiveness, don't go for "perfect" decisions. When your creative process leads to any feeling of relief, consider it a green light for a good enough decision. You can always amend your decision later.
