But let's look at her rocking stim. That has got to be causing spinal issues and head issues, neck issues too. How do you protect a person from that when they won't wear a padded vest or a helmet?
The biggest thing again is harm reduction/redirection. Now, I'm gonna be honest here. I'm very good at my job but Abbie would be a huge challenge (I usually do earlier intervention). So much in this poor girl's life is just
wrong, I'm honestly not sure where I would start. I guess setting up a hanging swing in her room and swing set out back would be a good place. Daily walks (plural). Get her in to a PT and then daily exercising those muscles, tendons, etc. Check her eyes, ears, etc. (I simply do not believe they've done this recently). Get her on a routine. Work on basic hygiene. CHANGE HER DIET. Hand exercises, hand/eye coordination, fine motor skills. Introduce sensory play again (avoiding sand, clay, anything she can try to eat). Introduce all of this stuff at a slow but steady pace (it would take years). Stop getting her to do useless tasks. Work with her emotionality. Pay attention to her.
If there was any way I could get her into a compression vest or neck brace while trying to fix everything else, I would do that, but you got to pick your battles sometimes.
And in my opinion, the best strategy of all would be to get her new parents (or put them in boot camp with an OT that knows what the hell they're doing). Let's face it, A&P are lazy as fuck and all of this requires effort and dedication.
