finding a story series.

I am trying to find a story series here on this site. I can't remember the author's name but it dealt with a teen who transitioned, and got some grief from his dad, older brother and grandfather, but they all came around eventually. She spent a lot of time dressing up at her grandmother's house. Also the grandmother gave the older brother a bit of petticoat discipline and he was tormented by his friends and defended the younger brother. I would be very grateful is somebody could help me find this story.
