Sign of autism???

This could be him stimming x

My child used to do a similar thing but not as fast? He used to lie on his back and basically do crunches with his legs? However he grew out of it. I was worried it was stimming or a form of epilepsy. Got him checked all was fine he was just being a weird little guy! I would show this video to a GP for your own peace of mind

He’s a baby. Autism is not diagnosed until a much older age for this exact reason - what is considered autistic traits in an older child is completely normal behaviour for a baby.

My 7 month old does the same all the way to me sitting him up.
I think some kids are more chilled with development than other, my 3yr old was practically crawling by 6 months, whilst my 7 month old just seems content with taking his time.
My 3yr used to flap like that, now he's 3yr with normal development.
I think as parents we can get worried over the little things, which is good because it shows we care. But, if we have health visiters, we have to trust they know our child stage of development.
Also, i think it's called stemming, but stemming doesn't necessarily indicate autism in children younger than 1.5
Hope that helps

I was worried about this weird stiffening thing my LO used to do and thought something similar. Different to this, but similar thoughts and worries. I showed a few videos to the GP and they consulted with a paediatrician who literally responded with "just looks like an excited baby" lol. He's stopped doing it now he's over a year. He has also been somewhat behind his peers with gross motor skills, but he's still getting them: crawled at 11 months, pulled to stand at 13 months, starting to cruise at 14 months. No worries from private physio we saw. I'd reach out to a medical professional for peace of mind, but it's probably nothing to worry about😊

Of course it can be stimming but it’s too early to tell.
My son used to sit on his butt (like a yoga butterfly position) and rub his feet together really really fast, like 5 times a day. My doctor said she’s not worried, it just looks like a happy baby. He stopped doing it a while back. So I think kids just do weird movements when they are excited.

He also could just have lots of energy but doesn’t know how to expend it! He can’t run around yet so he’s just “letting it all out”

This seems to be normal especially as young as 8 months. As you stated he has very good eye contact, hears his name and noises etc I don’t see a concern and appears normal behaviour

I’d be more concerned with the delayed milestones - have referrals / tests been put in place ?

That looks like frustration to me.. my boy does it when he’s super frustrated, except he does it stood up! 😅 could be that maybe there’s something hurting his back or head when he’s lying down. Try lying him on his side and feeling his spine to see if he reacts the same way sat up.

autism won't show really until after 12 months. the main signs are regression, eg, no longer talking or babbling, no eye contact, not responding to his name, hand flapping, sensory seeking behaviours.

- raised around at least 7 people with varying levels of autism with a mother who's an OT

Either way , you can’t do anything to ‘cure’ autism and he wouldn’t get diagnosed for a white yet so try not to worry ! If it’s not harming him , let him continue for a bit then try distract him xx

My son wasn’t cuddly at that age as he’s got older that’s all we get now is cuddles ! He’s now 1 years old , don’t over think it
