you must empty yourself
of your constant thinking,
planning, and worrying."
There was a webcomic I read once (Sinfest) which stated that "fear trumps hope." They demonstrated this by turning on the T.V. to the news, spreading rumors, doing research on natural disasters, the oil disaster, global warming, talking to Christians about Armageddon, showing military footage, etc...
As a parent, the information age is loaded with fearmongering. Parents are informed that you can't trust any stranger, that laypeople will try to abduct your children. There are crib recalls, toy recalls, food recalls... parents need to worry about BPA in plastic, lead paint, allergy-triggering foods, non-organic foods, organic foods, vaccine-preventable diseases, reactions to vaccines, chemicals, etc... Parents are worried about having toys in the baby's crib, choking hazards, making sure car seats are safe, and preventing SIDS.
Is it practical, useful, and beneficial to inform yourself? Of course! However as parents our fear, worry, and guilt can easily take over our lives. A mother's and father's protective instinct can easily go into overdrive, tempting them to never allow their child to play outside, eat foods with red dye, or be left alone with relatives.
I'm not advocating for perfect trust in the world. The world is an essentially untrustworthy place. However, parents need to overcome their compulsions to shelter their kids, otherwise we run the risk of an early death of heart attacks and high blood pressure, and taking all the joy out of life for our children. A child needs to be able to run barefoot through the grass, climb trees (at the risk of a broken limb), and enjoy a cool watermelon on a hot summer's day without his/her parents trying to comb through the fruit to remove all choking-hazard seeds.
The world can be a scary place, but it's also a very beautiful place. Show your child the beauty of it. And while you're at it, show yourself.
