We've had a heckuva time coming up with a name for our second baby (if it's a boy). We were attached to our girl name and we had a son first, but we felt like we used our favorite and everything else felt second best. I did a ton of internet research and just wasn't coming up with anything we both loved. With that said, we started using a book called "The Baby Name Wizard" and love it! Even if you don't find the name of your dreams, it definitely gets the wheels turning with the different categories of names that you might not have been able to pick out yourself. Plus, the sibling suggestions are great
Good luck!
