Thank you for the input, ladies :)
Yes, I agree, it's a pretty name. A competitor will come along and there will be something else to replace Alexa soon. I wouldn't let that stop me. One thing I did check was how common a name was with other moms. I didn't want my kids going to school with lots of other kids of the same name--- I had that growing up and had to use my middle initial or middle name always in school as I had a common maiden name as well. I like traditional but not names everyone has. I don't know any alexa's. It's definitely a pretty name.
