9mo old doesn’t respond to name

Hi, I’m a FTM. I noticed my 9mo son doesn’t respond to his name most of the time. He responds to noises, or if I sing, but otherwise seems to either not hear me when I say his name or ignore me. He also doesn’t clap, point, or wave. He does babble a little, but usually not when he’s looking at you. I have a niece with ASD, so of course I’m already concerned and paranoid that he’ll have it too. I know he’s still young, and i shouldn’t be concerned until he’s 12mo, but I can’t seem to stop worrying. I guess I’m just looking for other parents who had/have babies who were like this, and what the outcome was? Thanks I’m advance
