Not a problem!
The sad thing is that there are so many parents who take the opposite approach and try to force their child to fit into the traditional binary construct. However, some kids just necessarily fall outside of that and you can’t force fit them into what society expects. Such parents never seem to think about the extraordinary harm that they cause.
Again, I commend you as a parent. Kicking a kid out of the house is easy, but doing what you are doing takes considerable effort, courage and conviction. Many trans kids would kill to have such a parent and I’m pretty certain that you and your son will have a positive outcome!
Best of Luck!
