Honestly I’m astounded by some of these batshit replies! People are forgetting at the centre of this debate is a child. A child who is struggling, who confused, who needs support love and a mum who they can open up to. Don’t force them to regress and internalise their struggles, the fact they have managed to verbalise what they think they feel to you is amazing and hold on to that. You need to nurture their emotional health , don’t come down hard don’t push them away. Don’t force anything either way. Just listen, follow their lead and gently guide. It’s not wrong to have open conversation’s and question their logic, but do it while being open. Unpick it together and always be available.
He needs help unpicking it all, it’s not about whether or not people believe in sex or gender. It’s fucking irrelevant it’s about supporting an emotionally and socially vulnerable child at a critical time. To push away your preteen by saying what they think and feel is wrong, is to push your preteen away, make them feel unloved and isolated and will only reaffirm their feelings that they don’t fit in this world. And what will happen then ? They will seek this else where and go down a rabbit hole and find this in people who don’t have their best interest’s at heart. That’s dangerous!
I can guarantee you now op the people who are saying you should tell him he is boy end of story, have no real life experience in this department - and if they do I can bet they have very unhappy children. I’ll say it again don’t encourage him, just follow his lead, you don’t need to do anything except listen , to him love him not matter what and gently guide by setting some boundaries. That’s okay! Even children who arn’t struggling with their identity need boundaries around what’s appropriate and what’s not. For example, my youngest daughter isn’t allowed nail extensions or fake eyelashes because she is 11 not 15.
I’d also get some counselling for your son, I’d avoid the ones specifically aimed at gender identity struggles I don’t think that is necessarily important. I got my child some through a young people’s mental health charity, just gives them another chance to talk about their feelings without judgement. Good luck OP.
