hi shamala kiran ji its me Aes kay i want tio ask is watching tv and listenring music delay language skill of 9 month old baby

To a certain extent, yes. Babies talk soner and clear if they experience conversations. The more you talk to your baby in clear words, the more babies learn. You can use music to sing together, rhymes or songs and speak out each word slowly and clearly.
I am not in favor of TV for so young babies but I know some people do feel it helps too.

okk but now i decided for no tv atall..
