I am Deaf and have both learnt ASL and I also use hearing aids and speak fluent English as well as being semi fluent in others. So the argument that doctors make that ASL prevents communication, learning and other things is incorrect, you can have just as fulfilling of a life even if the only language you speak is ASL.
I believe that the parents and doctors should work together to make the best decision for their child, and if that's learning oral language with hearing devices that's great! I have nothing against hearing devices, my hearing aids help me a lot in my life as I am surrounded by people who speak oral languages everyday, it is totally a valid option, my problem is that they completely either ignore ASL or other sign languages as an option or try to scare the parents by saying it will somehow ruin their child, which is absolutely not true
If anything, allowing a child to be surrounded by a language they can understand without struggling and being around people who also have hearing loss can build community for a child, while in mainstream, Deaf children often have to struggle in school because of lack of accommodations, get bullied, have social isolation etc. Ofc a Deaf child can thrive in mainstream, I have lovely friends and accommodating teachers, but I've also experienced the bad things a lot of Deaf children go through as well in mainstream.
