is this normal for ds 3.6 or should I be as worried as I am?

Ok I've worried myself stupid about ds's behaviour recently and now don't know if i'm worrying too much (have a tendency to do this). Ds has been displaying some behaviours that I sometimes think could be perfectly normal for a 3 1/2 year old boy but maybe not iyswim.
Ds is very lively and laughs a lot of the time - finds things hilarious and really chuckles which is lovely. He has a tendency to go ott when with friends chasing and laughing hysterically which the others don't do. Sometimes he can be a bit too much in their faces (only with 1 or 2 of his close friends)and can sometimes pull a strange face while doing this. He also does this to his sister who is 12 weeks. Often comes up to her and strokes her head or shakes her hand with a strange expression on his face - he does this a lot throughout the day.
Meal times when with friends have become embarrasing. He'll suddenly throw his arms up in the air or put his hands on his head. I think this could be showing off as it's when there are other people around but it looks odd. Sometimes he'll stop when asked.
Trying to get him to go for a poo has become odd too. I think he's always suffered with a bit of constiaption and tends to hold on to his poos for a few days before having to go. When he does go he writhes around on the loo can flap his arms a bit and talks absolute gibberish - almost like a foreign language. We asked him not to do it the other day and he managed to go normally. He also sometimes bangs his hands on the table or waves his arms for a short amount of time if he's eating something he doesn't really want to.
So those are the bits that are worrying me.
Apart from these behaviours he's perfectly great. Plays with his toys, plays with other children imaginatively, never shys away. Doesn't have any repetetive behaviours (except maybe for the touching his sister thing). He's reached allother mile stones for his age.
I spoke to nursery about him and they said he's just a normal boisterous boy and that he will learn to control this as he gets older. They only see him for 2 hours a day and I'm sure he's so engaged in what he's doing when he's there they might not see some of the behaviours dh and I worry about.
So anybody had similar behaviours or any advice for a seriously worried Mum?

That's totally normal, don't worry-dd does this and a) she is a girl and b) is nearly 5, and she can't always stop when asked! Gibberish talking is always normal-she makes up her own languages and then giggles when people can't understand her!

Sorry you are so worried...

I am not an expert but have boys of 4 and 3 who AFAIK are NT. They do all the stuff you mention in your first 3 paras...chasing laughing hysterically, being boisterous, trying to pick up babies (the 3yo )and generally showing off

so dont knwo if its normal but mine do it

i know a boy of 2 years and 11 months and another of 4 years old, both of them do the same things tbh. doesn't sound anything to worry about at all, he sounds bags of fun. the fact that he can stop doing these things when asked means he is in control of his nehaviour. all sounds very normal to me though, little boys are just funny little creatures!

I have a four year old, three year old and an 11 week old, and the three year old sounds like your ds - it's a difficult age, no longer a toddler, but not old enough to control their behaviour very while or to reason with them.

Flapping arms around, pulling faces and talking gibberish is in most children normal.

Perfectly normal for him to repeatadly touch, poke, try and pick up, pull his baby sister.

I wouldn't worry about any of it.

Thanks all.
Sadly I'm one of life's worriers, but you've put my mind at rest.
