Not responding to name at nine months

[Parkbench123]

Hi, my 9month son has never responded to his name even when I say it repeatedly, but has excellent hearing - wakes up or stops feeding at the slightest sound. He also won't look where I'm looking or pointing. His eye contact is very good when he wants to and shocking when he's more interested in something else. He's very smily. He has imitated me clapping or waving in past, but hasn't these past weeks. As a first time mum, I'm worried about autism. Anyone else had a nine month old like this, but ended up ok? My internet search just screams "your child has autism" to me!

@Rd03 thank you gor responding.eventhough my baby also had bad reflux,but its hard to relate those communication delay with reflux.
We have been using her name from last 3/4months continuously still its not stiking it with her.But feels strange she immediatly turns to Alexa,fan, ball etc when i say it.which makes me worry more.
she do have nice eye contact and that is the reason pediatriaction dismiss my concern mostly.
But I can see so many red flags:
she donot respond to name at all not even 1time (but looks when sound is coming from somewhere new and that is definetly responding to sound not name,but prople wont believe me and tell me I am overthinking) ,
she is playing repeatedly with her toys in non functional way like she flips her piano back and forth continuously rather than playing with piano,
she is not so much cuddly baby,
she has started flapping hand these days been a week she is flapping hand and making body rogid whenever angry or excited,
she is not much into babies of her age,
no any gesteure except clapping and raisking hand for pickupand she sometime mimics we tapping/scratching on floor thats it.

all these things makes me worry more and more each day.Not been able to sleep and do my norma activity since couple months.I have contacted early intervention and she is in speech therapy but it is not showing any progress on her.I am also waiting for therapy for myself ue to my current mental state and anxiety.
please update me what her pardiatriacian says about these things.Thank you in advance.

@Saiaryal24 Hows your Daughter now? My DC is 9 months and his social and communication development I feel is behind. I have my 9-12 month HV review next month and hoping he may catch up by then but in comparison to children at my baby class, I get worried

@Holly96xo hi. I wonder how is your second son doing? Does he respond to his name?

@Ariana1371 Hi. I wonder how is your daughter doing? Thanks

@Yas1362 Hello, my daughter is doing great she had diagnoses of ADHD which affects her focus but she is ahead of her peers academically. I worried to death but now I regret it, I could not enjoy when she was a baby.
