My daughter, since she was small had a habit of flopping down to the ground and sitting there while laughing - usually it was during times of change, family members or friends saying goodbye when leaving our house - sometimes it would be when we had visitors and lots of people talking. She never showed signs of distress but would laugh uncontrollably almost like she was acting for laughs. I never thought anything of it as she was always very bubbly and happy when small and people just assumed this was all part of her character. She seemed to love attention on her. But, now that she is older she still occasionally does this with us. Again when she is at home and saying goodbye to someone at our front door.
But she has also done this when out in public when she was at the cinema with 3 of her friends. This last episode was very noticeable that it was odd behaviour to her friends who were all looking at her and showing their impatience with her as she wouldn't get up and was just laughing and sitting/laying on the floor. I was with them and asked her quietly to get up off the floor (people were all leaving the cinema and having to walk around her). I can't find anything that explains this behaviour or links it to ASD but has anyone seen similar in their child and is this overwhelm? I am now thinking it is but I never recognised it before but I cannot find any evidence or examples that explain it. She generally shows overwhelm by shutting down and internalising and naturally masking extensively. She does have dyspraxia but I don't think this is a balance or coordination issue as she is often just standing there and flops down.
