Normal baby behaviour?

[Whisper92]

My nearly 9 month old baby has a strong dislike to loud noises.
For example, yesterday his dad sneezed 3 times really loudly near him whilst he was changing his nappy and he became absolutely hysterical.
We also walked past a police siren and he started screaming.
He screams if people laugh loudly near him too.
He calms down after a cuddle and a couple minutes but I’m wondering if this is normal or a sign of autism? As I’ve heard online it is, but he doesn’t appear to show any other signs so I’m not sure if its worth mentioning to the health visitor or if it’s just his personality?
He is a Pisces if that makes any difference! (They are supposedly super sensitive.)

Gosh

it’s normal op. Please step away from reading what’s normal online

I’m really not mocking you or being mean - but it’s worrying times where we suspect autism in babies who are displaying perfectly normal behaviour. Why do we feel like we have to label everything nowadays?

Please try not to worry. We went through a phase of having to extend sneezes in a comical way or DD would cry: “achoo-ooo-ooo-ooo smile giggle giggle”. You could try acknowledging the noise, and talking about it, positively, so he knows it’s a bit loud, but nothing to be scared of, especially now he’s getting older and understanding more. “Oooh, that was a bit loud wasn’t it?! Nee naw, nee naw, what a loud ambulance!” Now when there’s a loud noise, DD (22m) turns to me and says “it’s a bit noisy”, sounding exactly like my mum; clearly I’ve been channeling her in my parenting chat!
