I don't think there is much to discuss here.
If your 5 year old son starts to wear girls clothes you should let him do that, maybe this is just a phase maybe not. You shouldn't push anything upon your child but you should support the decicions they make. If your child still holds those beliefs at the start of puberty, you should visit a doctor with them and talk about a hormone therapy. Hormone therapies are as far as I know not irreversible so if your son, after two years of hormone therapy suddenly changed his mind, the therapy can stop and he will have a delayed but normal puberty, if not he can decide to fully transition once he's 18.
