Wow Harley is a very pretty name I love it. You have to ignore people sometimes they tend to think they have to give opinions on everything. If they didn't like her name they could've simply kept quiet. As long as you and her father like it that's what matters.
It's your baby. You can name her what you want. I wouldn't let people being mad at me faze me... I had everyone especially my bd mom telling me what to name my child and saying all the names I liked was ugly. But I named my son what I wanted regardless and pissed everyone off. who cares lol
