he’s 13, 13 year olds are influenced easily and want to hop on the “being different” train. instantly, my first reaction would be to ask him why and tell him the ruling on it islamically and tell him it’s impossible for him to be a woman, but gently. then when he’s asleep i check his phone thoroughly, to see how or why he’s being affected. at 13 he doesn’t need a phone other than to call or contact me or his friends so i will enforce a rule for him to be off the internet - and replace his phone with a simple brick burner , qnd monitor access otherwise .
it’s important to do this in a gentle way that doesn’t seem like a punishment - if my son troons out that’s my fault for not raising him better. i will bring him to manlier environments and put more manly figures into his life who will influence him for the better - and hope this helps for therapy. giving the troon thing too much attention would encourage it bc sometimes kids just like doing things you don’t like , so it would be on the lowkey.
but punishment shouldn’t be the answer - because your child told you how they felt and even if it’s nasty and you want to hurt them for it , realise it’s not an original thought and your kid is being influenced and this is a cry for help.
