She's a girl. No question about it and no need to doubt you are on the right path! I have worked with other Trans families like yours and I applaud all of you for your fierce protection of your Trans-child. I've watched a generation of supported Trans children grow into happy confident and loved adults. It's the most beautiful thing to see after growing up in an era with zero awareness or tolerance of our community. I celebrate you and your daughter, and want you to know you are absolutely doing the right. thing for your child! Brava!!
