My brother (8) isn't normal and I don't know how to help him
Hey im a girl (18) I have a younger brother let's call him Mike and he doenst have any disabilities or conditions as far as I know but he behaves in what i can only describe as weird ways .He still doenst speak that clearly and mixes up sounds , he cant tells stories or talk in the "mature" way that kids do at that age .he hasn't had much social interaction since birth as my parents were always busy so he mostly grew up on unsupervised media which probably is the root cause of his behaviour .he does inappropriate stuff like scream or behave in ways similar to a much younger child and he doenst really comprehend most things .
I suspect that most of his behaviour stems from undersocialization since he just doesn't understand norms and how to behave .now I wanna be clear I love my brother ,like much more than my other brothers but sometimes Idk how to deal with him and I scold him or say no to alot of things to help him fit in .when other kids are playing he cant really join them since he doenst know how to interact with them and they always ask me why he talks like that which is when I try to tell Mike to stop saying some things but I can see it hurts him .
I don't want him to be hurt but I dont wanna enable bad behavior either .I honestly just don't know what to do , I've been trying to make my parents take him to a child therapist since he was 4 and didn't speak but they still ignore his issues and say he'll grow out of them . I want him to be happy and have friends and not be bullied but I also don't know how to help him .furthermore im going to uni next yr and then he'll be all alone and I know my parents will just let him use his phone all the time making it worse .if anyone has gone thru something similar or knows how I can help him please let me know , I haven't always been a good sister but im really trying .thankyou
Edit : I think the cultural differences between my country and the commenters is too significant so please don't judge my parents too harshly this definitely isn't somewhere I came for real answers I was more just looking for validation that im not crazy and making a big deal out of nth .
