Unsure how to title this so bear with me whilst I explain please.
My ten year old step daughter displays pretty regressive behaviour at certain times - usually when stressed, or anxious, but also towards the end of the day - we read in our bed and she does it then.
I'm talking about things like thumb sucking, hair stroking, regressive communication, regressive emotions (ie. she does not display her emotions as she would at other times of the day).
She's been assessed and diagnosed with a learning difficulty (which it turns out may not be as mild as we were originally told), she struggles with processing and sequencing. This has some pretty big knock on impacts - the ones that have caused the argument are regarding toileting and bed wetting. Not really sure how to describe the toileting ones but it as if she doesn't listen to the signals; it can be pretty brutal and the pandemic has made things worse. She wets the bed every single night without fail and we've tried everything - she now wears drynights. She's also been diagnosed with encopresis.
Everything has come to a head because I've been away and my dipshit partner (dipshit for multiple reasons) decided to go all out, no drynights, strict regime, possibly some shouting, if she doesn't strip the bed then it stays that way. Frankly, I feel gross behaviour.
It's had a huge knock on affect on her and she's displaying regressive behaviours, super clingy, been a nightmare in school (which is not like her) etc.
I just need to know if I stand up to him and tell him how batshit he is or if he actually has the right method and I need to stand by him and hope things get better.
