What's Your Name?

I'm always looking at the milestone charts and guidelines online. Right around now my daughter should be starting to respond to her name. So today I spent a large portion of my time calling her by name to see if she would respond. While I was doing this (and she wasn't responding) I remembered that I rarely call her by her name. I call her bug 90% of the time and then the rest of the time she's babe, sweetie and occasionally her actual name. Great. My child thinks her name is bug. What have I done??
