Hiding under the table

[Hasstrictlystartedyet]

If we take Dd, just turned 4 out for a meal etc, she hides under the table. She isn’t shy at all, very outgoing etc.
Is this normal?

Introverts can still be happy, outgoing, confident children, but suddenly hit a wall and need some time alone.
My DD used to do this sometimes at parties when it all got too much. She's a teen now and still needs quiet, alone time - especially if she's been around people being sociable.

I'd still leave her, she's not upsetting anyone. She will eventually sit at a table
Speak to her and see how she felt about it

So she is being disobedient. Where is the point when you say 'If you don't do as you are told we are going straight home and/or you lose privileges'.

She's doing it because it's a fun game for her and you keep letting her do it. It's a novelty. Kids tend to like sitting under things like that; it's similar to the way they like 'hiding' in tents or Wendy houses or in little camps they've built. She wouldn't be allowed to do that at school/nursery/pre-school and at home it's not a novelty.

I don't know any ASD kids whose condition manifests itself solely in sitting under a table in restaurants. Not everything is a symptom of a condition or a disorder.

Speaking as a massive introvert, this doesn't sound anything like an introvert 'hitting a wall' to me, because she is only doing this in restaurants and apparently in literally no other social environment. Also - again speaking as a massive introvert - introversion isn't an excuse to behave badly.

It could also be an attention seeking behaviour? Family meals are not necessarily the most interesting thing for a 4 year old..I would ignore it, especially if she's not disruptive, but then make a fuss (in a good way) when she comes out. If she's otherwise well behaved etc, ignore the behaviours you don't want and reward the ones you do.
