Nervous laughter

[MotherDearest123]

DD has a nervous laugh I think am di want her to be able to control it so she doesn’t get in more trouble . For example when being told off she iwlk snigger or laugh or when a situation is awkward . How do I help her stop this ? Does it ever go away

Surely this is very normal for teenagers? I used to do it. Have just about got over it now (age 53)

It’s excesisve though . None of her friends do it . She got told she’d be sent out if she laughed today and low and behold she laughed and her friends didn’t . She’s constantly being seen as rude or getting into trouble because of it and she hates it
