history: When I had my child, I felt like doing nothing but protecting her.  Having a child changed my life. I never imagined I could be so protective of something.  I have heard the same thing from my friends who have kids!  They say it's like a force takes over as soon as the baby is born
current: Yes you want to sheild them from everything bad and nurture them.
