4 year old behaviour. Neurodiversity?

[Inauthentic]

I posted this thread yesterday in "Being a parent" section and got replies from one person and then realised I might get more replies here.

My almost 4 year old boy's behaviour concerns me. Keeps running away from us and thinks it's funny..
We went out for lunch and cinema today and I am exhausted. He lasted one hour in the restaurant and then kept running away from the table. On the way to the cinema ran on the escalator and tried to sit on the stair, he was all over the place and we had to chase him and grab him a lot. It was not possible to discipline him, he thinks it's funny and just does his own thing.
My partner lost his cool and didn't go to the cinema - he later told me he felt like spanking him.
I took him in and after 30 mins he started wandering between seats. We ended up leaving the cinema.
Is this "normal" or should I be worried?

I think with one example it’s impossible to say. What’s his behaviour like in general?

Expecting a four year old boy to sit more than an hour in a restaurant is a tad unrealistic and then sitting in a cinema for a film afterwards, it’s really not surprising he wanted to move about tbh.

Running away from us is a pretty regular behaviour, he often acts like that. In the park, town etc.
Bedtime routine is often exhausting, we often have to chase him as he doesn't want to put his pyjamas on/brush his teeth.

His nursery commented on repetitive movements he does which could be "stimming".
I did some research long time before their comments and I think it might be motor stereotypies.

They also mentioned before that he is not very good at putting his shoes and coat on and lagging behind other children when getting ready to go out. They asked if he could practice it at home/do it it for himself
I have to admit we used to often do that for him because of morning rush. But now encourage him to put his shoes everytime. He doesn't always listen but he is better at it
Otherwise no concerns were raised by nursery

Here’s an article on checklists for ADHD. If you haven’t already looked at something like this it’s worth seeing how many boxes he ticks. Lots of these online.

Symptoms of ASD are problems with social communication and repetitive behaviour. These can vary in range but need to be to the extent that they impact on everyday life.

Obviously there are other types of neurodiversity.

Thanks @openupmyeagereyes
I had a look, I read lots of similar stuff before.
Some days I think his behaviour is fine but some days I seriously consider he might be neurodivergent.
It's the uncertainty that makes me anxious

He’s still very young and boys are generally more active and rambunctious. I would keep a note of anything that you think is unusual and not typical so that if you do get to a point where you’re more concerned you have evidence to back it up.

Are you expecting to much of DS? Many 3 year olds wouldn’t be able to sit through a film at the cinema after also sitting in a restaurant.

If DS can’t be trusted not to run off and you are struggling to hold onto him when holding his hand have you thought about reins?

Our local cinema has a kids club but only for 5 year olds up to 10 years old....theres a film on there which is shown in half...then a break for drinks and play for the kids getting bored..then when they all sit again the film Continues
There view is under 5s will not sit still so they dont accept them
