@Curlyhairedassasin - do the team have a rationale for why they think removing the scale is important now? Are they trying to tackle rigidity or something? If I were you I would be tempted to go back to weighing it for the time being, knowing she is steadily gaining, with the hope that once she is more weight restored she will find it easier to cope with the anxiety about eating fat unweighed.
We tend to just 'make' dd eat what we say (she doesn't know how much fat and calories are in her foods) and weather the aggression and bad behaviour etc (when I say weather it, I find it completely upsetting and draining), but if any of my other kids were being unsettled to a greater degree than they already are then we would take a different approach. You have to do what's ok for your whole family... Surely your ed team should be helping you figure out what that might look like? Ironically sounds like they are trying to tackle rigidity by being rigid!
Maybe tackling the weighing thing, and other 'rigidity' can happen in a compassionate way in the future, but at the moment my focus would only be on gain personally. If someone is neurodivergent, being rigid can be about trying to cope with anxiety usually, and so that needs thought - stripping things away isn't usually a good way of making someone feel better, and especially in a brain that's not yet weight restored.
@NanFlanders - oh that's amazing about the advent!! I dodged it this year and just got a non food one because I had no brain space to think it through. Well done you and your dd ❤️
